Device, method, and graphical user interface for moving and dropping a user interface object

ABSTRACT

An electronic device detects a contact associated with a focus selector that controls movement of a respective user interface object; and while continuously detecting the contact, the device detects first movement of the contact. In response to detecting the first movement of the contact, the device moves the focus selector and the respective user interface object, and determines an intensity of the contact. The device detects second movement of the contact and in response to detecting the second movement of the contact: when the contact meets respective intensity criteria, the device moves the focus selector and the user interface object; and when the contact does not meet the respective intensity criteria, the device moves the focus selector without moving the user interface object.

TECHNICAL FIELD

This relates generally to electronic devices with touch-sensitive surfaces, including but not limited to electronic devices with touch-sensitive surfaces that detect inputs for manipulating user interfaces.

BACKGROUND

The use of touch-sensitive surfaces as input devices for computers and other electronic computing devices has increased significantly in recent years. Exemplary touch-sensitive surfaces include touch pads and touch screen displays. Such surfaces are widely used to manipulate user interface objects on a display.

Exemplary manipulations include adjusting the position and/or size of one or more user interface objects or activating buttons or opening files/applications represented by user interface objects, as well as associating metadata with one or more user interface objects or otherwise manipulating user interfaces. Exemplary user interface objects include digital images, video, text, icons, control elements such as buttons and other graphics. A user will, in some circumstances, need to perform such manipulations on user interface objects in a file management program (e.g., Finder from Apple Inc. of Cupertino, Calif.), an image management application (e.g., Aperture or iPhoto from Apple Inc. of Cupertino, Calif.), a digital content (e.g., videos and music) management application (e.g., iTunes from Apple Inc. of Cupertino, Calif.), a drawing application, a presentation application (e.g., Keynote from Apple Inc. of Cupertino, Calif.), a word processing application (e.g., Pages from Apple Inc. of Cupertino, Calif.), a website creation application (e.g., iWeb from Apple Inc. of Cupertino, Calif.), a disk authoring application (e.g., iDVD from Apple Inc. of Cupertino, Calif.), or a spreadsheet application (e.g., Numbers from Apple Inc. of Cupertino, Calif.).

But existing methods for performing these manipulations are cumbersome and inefficient. In addition, existing methods take longer than necessary, thereby wasting energy. This latter consideration is particularly important in battery-operated devices.

SUMMARY

Accordingly, there is a need for electronic devices with faster, more efficient methods and interfaces for manipulating user interfaces. Such methods and interfaces optionally complement or replace conventional methods for manipulating user interfaces. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges.

The above deficiencies and other problems associated with user interfaces for electronic devices with touch-sensitive surfaces are reduced or eliminated by the disclosed devices. In some embodiments, the device is a desktop computer. In some embodiments, the device is portable (e.g., a notebook computer, tablet computer, or handheld device). In some embodiments, the device has a touchpad. In some embodiments, the device has a touch-sensitive display (also known as a “touch screen” or “touch screen display”). In some embodiments, the device has a graphical user interface (GUI), one or more processors, memory and one or more modules, programs or sets of instructions stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI primarily through finger contacts and gestures on the touch-sensitive surface. In some embodiments, the functions optionally include image editing, drawing, presenting, word processing, website creating, disk authoring, spreadsheet making, game playing, telephoning, video conferencing, e-mailing, instant messaging, workout support, digital photographing, digital videoing, web browsing, digital music playing, and/or digital video playing. Executable instructions for performing these functions are, optionally, included in a non-transitory computer readable storage medium or other computer program product configured for execution by one or more processors.

There is a need for electronic devices with faster, more efficient methods and interfaces for previewing and selecting content items. Such methods and interfaces may complement or replace conventional methods for previewing and selecting content items. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges.

In accordance with some embodiments, a method is performed at an electronic device with a touch-sensitive surface and a display, where the device includes one or more sensors to detect intensity of contacts with the touch-sensitive surface. The method includes displaying a content field on the display and detecting a contact on the touch-sensitive surface, where the contact corresponds to a focus selector on the display. The method further includes, while continuously detecting the contact on the touch-sensitive surface, detecting a press input that includes an increase in intensity of the contact above a respective intensity threshold while the focus selector is over the content field, and in response to detecting the press input, displaying a content menu that includes representations of a plurality of options that correspond to content items. The method also includes, while continuously detecting the contact on the touch-sensitive surface, and while displaying the content menu, detecting movement of the contact that corresponds to movement of the focus selector over a representation of a first content item in the content menu, and in response to the focus selector being over the representation of the first content item in the content menu, displaying a preview of the first content item in the content field. The method further includes detecting a confirmation input while the focus selector associated with the contact is over the representation of the first content item in the content menu and, in response to detecting the confirmation input, inserting the first content item into the content field.

In accordance with some embodiments, an electronic device includes a display unit configured to display a content field, a touch-sensitive surface unit configured to receive user contacts, one or more sensor units configured to detect intensity of contacts with the touch-sensitive surface unit, and a processing unit coupled to the display unit, the touch-sensitive surface unit, and the sensor units. The processing unit is configured to detect a contact on the touch-sensitive surface unit, where the contact corresponds to a focus selector on the display unit and, while continuously detecting the contact on the touch-sensitive surface, detect a press input that includes an increase in intensity of the contact above a respective intensity threshold while the focus selector is over the content field, and in response to detecting the press input, enable display of a content menu that includes representations of a plurality of options that correspond to content items. The processing unit is also configured, while continuously detecting the contact on the touch-sensitive surface, and while displaying the content menu, to detect movement of the contact that corresponds to movement of the focus selector over a representation of a first content item in the content menu, and in response to the focus selector being over the representation of the first content item in the content menu, enable display of a preview of the first content item in the content field. The processing unit is further configured to detect a confirmation input while the focus selector associated with the contact is over the representation of the first content item in the content menu and, in response to detecting the confirmation input, insert the first content item into the content field.

Thus, electronic devices with displays, touch-sensitive surfaces and one or more sensors to detect intensity of contacts with the touch-sensitive surface are provided with faster, more efficient methods and interfaces for previewing and selecting content items, thereby increasing the effectiveness, efficiency, and user satisfaction with such devices. Such methods and interfaces may complement or replace conventional methods for previewing and selecting content items.

There is a need for electronic devices with faster, more efficient methods and interfaces for moving and dropping a user interface object. Such methods and interfaces may complement or replace conventional methods for moving and dropping a user interface object. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges.

In accordance with some embodiments, a method is performed at an electronic device with a display, a touch-sensitive surface and one or more sensors to detect intensity of contacts with the touch-sensitive surface.

In accordance with some embodiments, an electronic device includes a display unit; a touch-sensitive surface unit configured to receive contacts; one or more sensor units configured to detect intensity of contacts with the touch-sensitive surface unit; and a processing unit coupled to the display unit, the touch-sensitive surface unit, and the sensor units. The processing unit is configured to: detect a contact with the touch-sensitive surface unit, wherein the contact is associated with a focus selector that controls movement of a respective user interface object that is currently selected; and while continuously detecting the contact on the touch-sensitive surface unit: detect first movement of the contact across the touch-sensitive surface unit corresponding to movement of the focus selector toward a respective location; in response to detecting the first movement of the contact across the touch-sensitive surface unit: move the focus selector on the display unit in accordance with the first movement of the contact and move the respective user interface object in accordance with the movement of the focus selector, and determine an intensity of the contact on the touch-sensitive surface unit while the focus selector is at the respective location on the display unit; detect second movement of the contact across the touch-sensitive surface unit that corresponds to movement of the focus selector away from the respective location; and in response to detecting the second movement of the contact across the touch-sensitive surface unit: in accordance with a determination that the contact meets respective intensity criteria, move the focus selector and the user interface object in accordance with the second movement of the contact across the touch-sensitive surface unit; and in accordance with a determination that the contact does not meet the respective intensity criteria, move the focus selector in accordance with the second movement of the contact across the touch-sensitive surface unit without moving the user interface object.

Thus, electronic devices with displays, touch-sensitive surfaces, and one or more sensors to detect intensity of contacts with the touch-sensitive surface are provided with faster, more efficient methods and interfaces for moving and dropping a user interface object, thereby increasing the effectiveness, efficiency, and user satisfaction with such devices. Such methods and interfaces may complement or replace conventional methods for moving and dropping a user interface object.

DESCRIPTION OF EMBODIMENTS

The methods, devices and GUIs described herein provide visual and/or haptic feedback that makes manipulation of user interface objects more efficient and intuitive for a user. For example, in a system where the clicking action of a trackpad is decoupled from the contact intensity (e.g., contact force, contact pressure, or a substitute therefore) that is needed to reach an activation threshold, the device can generate different tactile outputs (e.g., “different clicks”) for different activation events (e.g., so that clicks that accomplish a particular result are differentiated from clicks that do not produce any result or that accomplish a different result from the particular result). Additionally, tactile outputs can be generated in response to other events that are not related to increasing intensity of a contact, such as generating a tactile output (e.g., a “detent”) when a user interface object is moved to a particular position, boundary or orientation, or when an event occurs at the device.

Additionally, in a system where a trackpad or touch-screen display is sensitive to a range of contact intensity that includes more than one or two specific intensity values (e.g., more than a simple on/off, binary intensity determination), the user interface can provide responses (e.g., visual or tactile cues) that are indicative of the intensity of the contact within the range. In some implementations, a pre-activation-threshold response and/or a post-activation-threshold response to an input are displayed as continuous animations. As one example of such a response, a preview of an operation is displayed in response to detecting an increase in contact intensity that is still below an activation threshold for performing the operation. As another example of such a response, an animation associated with an operation continues even after the activation threshold for the operation has been reached. Both of these examples provide a user with a continuous response to the force or pressure of a user's contact, which provides a user with visual and/or haptic feedback that is richer and more intuitive. More specifically, such continuous force responses give the user the experience of being able to press lightly to preview an operation and/or press deeply to push “past” or “through” a predefined user interface state corresponding to the operation.

Additionally, for a device with a touch-sensitive surface that is sensitive to a range of contact intensity, multiple contact intensity thresholds can be monitored by the device and different functions can be mapped to different contact intensity thresholds. This serves to increase the available “gesture space” providing easy access to advanced features for users who know that increasing the intensity of a contact at or beyond a second “deep press” intensity threshold will cause the device to perform a different operation from an operation that would be performed if the intensity of the contact is between a first “activation” intensity threshold and the second “deep press” intensity threshold. An advantage of assigning additional functionality to a second “deep press” intensity threshold while maintaining familiar functionality at a first “activation” intensity threshold is that inexperienced users who are, in some circumstances, confused by the additional functionality can use the familiar functionality by just applying an intensity up to the first “activation” intensity threshold, whereas more experienced users can take advantage of the additional functionality by applying an intensity at the second “deep press” intensity threshold.

Additionally, for a device with a touch-sensitive surface that is sensitive to a range of contact intensity, the device can provide additional functionality by allowing users to perform complex operations with a single continuous contact. For example, when selecting a group of objects, a user can move a continuous contact around the touch-sensitive surface and can press while dragging (e.g., applying an intensity greater than a “deep press” intensity threshold) to add additional elements to a selection. In this way, a user can intuitively interact with a user interface where pressing harder with a contact causes objects in the user interface to be “stickier.”

A number of different approaches to providing an intuitive user interface on a device where a clicking action is decoupled from the force that is needed to reach an activation threshold and/or the device is sensitive to a wide range of contact intensities are described below. Using one or more of these approaches (optionally in conjunction with each other) helps to provide a user interface that intuitively provides users with additional information and functionality, thereby reducing the user's cognitive burden and improving the human-machine interface. Such improvements in the human-machine interface enable users to use the device faster and more efficiently. For battery-operated devices, these improvements conserve power and increase the time between battery charges. For ease of explanation, systems, methods and user interfaces for including illustrative examples of some of these approaches are described below, as follows:

-   -   Many electronic devices have graphical user interfaces that         display content items (e.g., a photo in a photo album). Content         items can be customized in various ways, including, for example,         selecting, previewing or rearranging photos within a photo         album. Such operations often require multiple sequential inputs,         which can be time consuming and confusing for users. The         embodiments described below provide a convenient and intuitive         method of previewing content items and selecting previewed         content items in accordance with an intensity of a contact. In         particular, FIGS. 5A-5N illustrate exemplary user interfaces for         previewing and selecting (e.g., in accordance with user inputs         on a touch-sensitive surface) content items corresponding to a         content field in accordance with some embodiments. FIGS. 6A-6C         are flow diagrams illustrating a method of previewing and         selecting (e.g., in accordance with user inputs on a         touch-sensitive surface) content items corresponding to a         content field in accordance with some embodiments. The user         interfaces in FIGS. 5A-5N are further used to illustrate the         processes described below with reference to FIGS. 6A-6C.     -   Many electronic devices have graphical user interfaces that         allow a user to move a user interface object, such as an icon.         Sometimes, a user will be required to perform multiple         sequential input operations to move a user interface object such         as clicking, dragging, and unclicking to drop. This can be         time-consuming, confusing, and disruptive to a user's         interaction with the device. The embodiments described below         provide a convenient and intuitive method of moving user         interface objects and ceasing to move user interface objects         based on intensity of a continuously detected contact, thereby         providing a more convenient and intuitive user interface for         moving user interface objects. In particular, FIGS. 8A-8J         illustrate exemplary user interfaces for moving and dropping a         user interface object. FIGS. 9A-9C are flow diagrams         illustrating a method of moving and dropping a user interface         object. The user interfaces in FIGS. 8A-8J are used to         illustrate the processes in FIGS. 9A-9C.     -   Many electronic devices have user interfaces in which multiple         operations are, optionally, performed with a same type of         gesture. In some situations, a user can switch between modes of         operation by selecting a different mode from a menu of options         or making a second contact in addition to the gesture for         activating the operation. However, these approaches to switching         between modes of operation are inefficient and confusing and can         be difficult for users to remember. The embodiments described         below provide a convenient and intuitive method of switching         between different modes of operation by selecting the mode of         operation in accordance with an intensity of an input on a         touch-sensitive surface. Below, FIGS. 11A-11W illustrate         exemplary user interfaces for performing an operation in         accordance with a selected mode of operation. FIGS. 12A-12D are         flow diagrams illustrating a method of performing an operation         in accordance with a selected mode of operation. The user         interfaces in FIGS. 11A-11W are used to illustrate the processes         in FIGS. 12A-12D.

Exemplary Devices

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described embodiments. However, it will be apparent to one of ordinary skill in the art that the various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

It will also be understood that, although the terms first, second, etc. are, in some instances, used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the scope of the various described embodiments. The first contact and the second contact are both contacts, but they are not the same contact.

The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

As used herein, the term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touch pads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touch pad).

In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse and/or a joystick.

The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user.

Attention is now directed toward embodiments of portable devices with touch-sensitive displays. FIG. 1A is a block diagram illustrating portable multifunction device 100 with touch-sensitive displays 112 in accordance with some embodiments. Touch-sensitive display 112 is sometimes called a “touch screen” for convenience, and is sometimes known as or called a touch-sensitive display system. Device 100 includes memory 102 (which optionally includes one or more computer readable storage mediums), memory controller 122, one or more processing units (CPU's) 120, peripherals interface 118, RF circuitry 108, audio circuitry 110, speaker 111, microphone 113, input/output (I/O) subsystem 106, other input or control devices 116, and external port 124. Device 100 optionally includes one or more optical sensors 164. Device 100 optionally includes one or more intensity sensors 165 for detecting intensity of contacts on device 100 (e.g., a touch-sensitive surface such as touch-sensitive display system 112 of device 100). Device 100 optionally includes one or more tactile output generators 167 for generating tactile outputs on device 100 (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system 112 of device 100 or touchpad 355 of device 300). These components optionally communicate over one or more communication buses or signal lines 103.

As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure).

As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user's sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user's movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

It should be appreciated that device 100 is only one example of a portable multifunction device, and that device 100 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in FIG. 1A are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application specific integrated circuits.

Memory 102 optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 102 by other components of device 100, such as CPU 120 and the peripherals interface 118, is, optionally, controlled by memory controller 122.

Peripherals interface 118 can be used to couple input and output peripherals of the device to CPU 120 and memory 102. The one or more processors 120 run or execute various software programs and/or sets of instructions stored in memory 102 to perform various functions for device 100 and to process data.

In some embodiments, peripherals interface 118, CPU 120, and memory controller 122 are, optionally, implemented on a single chip, such as chip 104. In some other embodiments, they are, optionally, implemented on separate chips.

Audio circuitry 110, speaker 111, and microphone 113 provide an audio interface between a user and device 100. Audio circuitry 110 receives audio data from peripherals interface 118, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 111. Speaker 111 converts the electrical signal to human-audible sound waves. Audio circuitry 110 also receives electrical signals converted by microphone 113 from sound waves. Audio circuitry 110 converts the electrical signal to audio data and transmits the audio data to peripherals interface 118 for processing. Audio data is, optionally, retrieved from and/or transmitted to memory 102 and/or RF circuitry 108 by peripherals interface 118. In some embodiments, audio circuitry 110 also includes a headset jack (e.g., 212, FIG. 2). The headset jack provides an interface between audio circuitry 110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

I/O subsystem 106 couples input/output peripherals on device 100, such as touch screen 112 and other input control devices 116, to peripherals interface 118. I/O subsystem 106 optionally includes display controller 156, optical sensor controller 158, intensity sensor controller 159, haptic feedback controller 161 and one or more input controllers 160 for other input or control devices. The one or more input controllers 160 receive/send electrical signals from/to other input or control devices 116. The other input control devices 116 optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 160 are, optionally, coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2) optionally include an up/down button for volume control of speaker 111 and/or microphone 113. The one or more buttons optionally include a push button (e.g., 206, FIG. 2).

Touch-sensitive display 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch screen 112. Touch screen 112 displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output corresponds to user-interface objects.

Touch screen 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch screen 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen 112. In an exemplary embodiment, a point of contact between touch screen 112 and the user corresponds to a finger of the user.

Touch screen 112 optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch screen 112 and display controller 156 optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 112. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.

Touch screen 112 optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user optionally makes contact with touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100 optionally includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.

Device 100 also includes power system 162 for powering the various components. Power system 162 optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 100 optionally also includes one or more optical sensors 164. FIG. 1A shows an optical sensor coupled to optical sensor controller 158 in I/O subsystem 106. Optical sensor 164 optionally includes charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 164 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor 164 optionally captures still images or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch screen display 112 on the front of the device, so that the touch screen display is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image is, optionally, obtained for videoconferencing while the user views the other video conference participants on the touch screen display.

Device 100 optionally also includes one or more contact intensity sensors 165. FIG. 1A shows a contact intensity sensor coupled to intensity sensor controller 159 in I/O subsystem 106. Contact intensity sensor 165 optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor 165 receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112). In some embodiments, at least one contact intensity sensor is located on the back of device 100, opposite touch screen display 112 which is located on the front of device 100.

Device 100 optionally also includes one or more proximity sensors 166. FIG. 1A shows proximity sensor 166 coupled to peripherals interface 118. Alternately, proximity sensor 166 is coupled to input controller 160 in I/O subsystem 106. In some embodiments, the proximity sensor turns off and disables touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

Device 100 optionally also includes one or more tactile output generators 167. FIG. 1A shows a tactile output generator coupled to haptic feedback controller 161 in I/O subsystem 106. Tactile output generator 167 optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor 165 receives tactile feedback generation instructions from haptic feedback module 133 and generates tactile outputs on device 100 that are capable of being sensed by a user of device 100. In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device 100) or laterally (e.g., back and forth in the same plane as a surface of device 100). In some embodiments, at least one tactile output generator sensor is located on the back of device 100, opposite touch screen display 112 which is located on the front of device 100.

Device 100 optionally also includes one or more accelerometers 168. FIG. 1A shows accelerometer 168 coupled to peripherals interface 118. Alternately, accelerometer 168 is, optionally, coupled to an input controller 160 in I/O subsystem 106. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 100 optionally includes, in addition to accelerometer(s) 168, a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 100.

In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, graphics module (or set of instructions) 132, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, and applications (or sets of instructions) 136. Furthermore, in some embodiments memory 102 stores device/global internal state 157, as shown in FIGS. 1A and 3. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 112; sensor state, including information obtained from the device's various sensors and input control devices 116; and location information concerning the device's location and/or attitude.

Operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Inc.) devices.

Contact/motion module 130 optionally detects contact with touch screen 112 (in conjunction with display controller 156) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact) determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

In some embodiments, contact/motion module 130 uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device 100). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined thresholds values without changing the trackpad or touch screen display hardware. Additionally, in some implementations a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter).

Contact/motion module 130 optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns and intensities. Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event.

Graphics module 132 includes various known software components for rendering and displaying graphics on touch screen 112 or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.

In some embodiments, graphics module 132 stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module 132 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 156.

Haptic feedback module 133 includes various software components for generating instructions used by tactile output generator(s) 167 to produce tactile outputs at one or more locations on device 100 in response to user interactions with device 100.

Text input module 134, which is, optionally, a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, browser 147, and any other application that needs text input).

GPS module 135 determines the location of the device and provides this information for use in various applications (e.g., to telephone 138 for use in location-based dialing, to camera 143 as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

In some embodiments, instant messaging module 141, rather than e-mail client module 140, is used to send a link to a particular online video.

Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 102 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 102 optionally stores additional modules and data structures not described above.

In some embodiments, device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 100, the number of physical input control devices (such as push buttons, dials, and the like) on device 100 is, optionally, reduced.

The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 100 to a main, home, or root menu from any user interface that is displayed on device 100. In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 102 (in FIG. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g., in operating system 126) and a respective application 136-1 (e.g., any of the aforementioned applications 137-151, 155, 380-390).

Event sorter 170 receives event information and determines the application 136-1 and application view 191 of application 136-1 to which to deliver the event information. Event sorter 170 includes event monitor 171 and event dispatcher module 174. In some embodiments, application 136-1 includes application internal state 192, which indicates the current application view(s) displayed on touch sensitive display 112 when the application is active or executing. In some embodiments, device/global internal state 157 is used by event sorter 170 to determine which application(s) is (are) currently active, and application internal state 192 is used by event sorter 170 to determine application views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additional information, such as one or more of: resume information to be used when application 136-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 136-1, a state queue for enabling the user to go back to a prior state or view of application 136-1, and a redo/undo queue of previous actions taken by the user.

Event monitor 171 receives event information from peripherals interface 118. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display 112, as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I/O subsystem 106 or a sensor, such as proximity sensor 166, accelerometer(s) 168, and/or microphone 113 (through audio circuitry 110). Information that peripherals interface 118 receives from I/O subsystem 106 includes information from touch-sensitive display 112 or a touch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripherals interface 118 at predetermined intervals. In response, peripherals interface 118 transmits event information. In other embodiments, peripheral interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit view determination module 172 and/or an active event recognizer determination module 173.

Hit view determination module 172 provides software procedures for determining where a sub-event has taken place within one or more views, when touch sensitive display 112 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (i.e., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

Event dispatcher module 174 dispatches the event information to an event recognizer (e.g., event recognizer 180). In embodiments including active event recognizer determination module 173, event dispatcher module 174 delivers the event information to an event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores in an event queue the event information, which is retrieved by a respective event receiver module 182.

In some embodiments, operating system 126 includes event sorter 170. Alternatively, application 136-1 includes event sorter 170. In yet other embodiments, event sorter 170 is a stand-alone module, or a part of another module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 191 of the application 136-1 includes one or more event recognizers 180. Typically, a respective application view 191 includes a plurality of event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 136-1 inherits methods and other properties. In some embodiments, a respective event handler 190 includes one or more of: data updater 176, object updater 177, GUI updater 178, and/or event data 179 received from event sorter 170. Event handler 190 optionally utilizes or calls data updater 176, object updater 177 or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views 191 includes one or more respective event handlers 190. Also, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g., event data 179) from event sorter 170, and identifies an event from the event information. Event recognizer 180 includes event receiver 182 and event comparator 184. In some embodiments, event recognizer 180 also includes at least a subset of: metadata 183, and event delivery instructions 188 (which optionally include sub-event delivery instructions).

Event receiver 182 receives event information from event sorter 170. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

Event comparator 184 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 184 includes event definitions 186. Event definitions 186 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (187-1), event 2 (187-2), and others. In some embodiments, sub-events in an event 187 include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (187-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (touch end) for a predetermined phase. In another example, the definition for event 2 (187-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display 112, and lift-off of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

In some embodiments, event definition 187 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 184 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display 112, when a touch is detected on touch-sensitive display 112, event comparator 184 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler associated with the sub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event 187 also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series of sub-events do not match any of the events in event definitions 186, the respective event recognizer 180 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata 183 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates event handler 190 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 180 delivers event information associated with the event to event handler 190. Activating an event handler 190 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 180 throws a flag associated with the recognized event, and event handler 190 associated with the flag catches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates the telephone number used in contacts module 137, or stores a video file used in video player module 145. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 177 creates a new user-interface object or updates the position of a user-interface object. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends it to graphics module 132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of a respective application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 100 with input-devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc., on touch-pads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized.

FIG. 2 illustrates a portable multifunction device 100 having a touch screen 112 in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure) or one or more styluses 203 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 100. In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap.

Device 100 optionally also includes one or more physical buttons, such as “home” or menu button 204. As described previously, menu button 204 is, optionally, used to navigate to any application 136 in a set of applications that are, optionally executed on device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen 112.

In one embodiment, device 100 includes touch screen 112, menu button 204, push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, Subscriber Identity Module (SIM) card slot 210, head set jack 212, and docking/charging external port 124. Push button 206 is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device 100 also accepts verbal input for activation or deactivation of some functions through microphone 113. Device 100 also, optionally, includes one or more contact intensity sensors 165 for detecting intensity of contacts on touch screen 112 and/or one or more tactile output generators 167 for generating tactile outputs for a user of device 100.

FIG. 3 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 300 need not be portable. In some embodiments, device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 300 typically includes one or more processing units (CPU's) 310, one or more network or other communications interfaces 360, memory 370, and one or more communication buses 320 for interconnecting these components. Communication buses 320 optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 300 includes input/output (I/O) interface 330 comprising display 340, which is typically a touch screen display. I/O interface 330 also optionally includes a keyboard and/or mouse (or other pointing device) 350 and touchpad 355, tactile output generator 357 for generating tactile outputs on device 300 (e.g., similar to tactile output generator(s) 167 described above with reference to FIG. 1A), sensors 359 (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s) 165 described above with reference to FIG. 1A). Memory 370 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory 370 optionally includes one or more storage devices remotely located from CPU(s) 310. In some embodiments, memory 370 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 102 of portable multifunction device 100 (FIG. 1A), or a subset thereof. Furthermore, memory 370 optionally stores additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 optionally stores drawing module 380, presentation module 382, word processing module 384, website creation module 386, disk authoring module 388, and/or spreadsheet module 390, while memory 102 of portable multifunction device 100 (FIG. 1A) optionally does not store these modules.

Each of the above identified elements in FIG. 3 are, optionally, stored in one or more of the previously mentioned memory devices. Each of the above identified modules corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 370 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 370 optionally stores additional modules and data structures not described above.

Attention is now directed towards embodiments of user interfaces (“UI”) that is, optionally, implemented on portable multifunction device 100.

FIG. 4A illustrates an exemplary user interface for a menu of applications on portable multifunction device 100 in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device 300. In some embodiments, user interface 400 includes the following elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),         such as cellular and Wi-Fi signals;     -   Time 404;     -   Bluetooth indicator 405;     -   Battery status indicator 406;     -   Tray 408 with icons for frequently used applications, such as:         -   Icon 416 for telephone module 138, labeled “Phone,” which             optionally includes an indicator 414 of the number of missed             calls or voicemail messages;         -   Icon 418 for e-mail client module 140, labeled “Mail,” which             optionally includes an indicator 410 of the number of unread             e-mails;         -   Icon 420 for browser module 147, labeled “Browser;” and         -   Icon 422 for video and music player module 152, also             referred to as iPod (trademark of Apple Inc.) module 152,             labeled “iPod;” and     -   Icons for other applications, such as:         -   Icon 424 for IM module 141, labeled “Text;”         -   Icon 426 for calendar module 148, labeled “Calendar;”         -   Icon 428 for image management module 144, labeled “Photos;”         -   Icon 430 for camera module 143, labeled “Camera;”         -   Icon 432 for online video module 155, labeled “Online Video”         -   Icon 434 for stocks widget 149-2, labeled “Stocks;”         -   Icon 436 for map module 154, labeled “Map;”         -   Icon 438 for weather widget 149-1, labeled “Weather;”         -   Icon 440 for alarm clock widget 149-4, labeled “Clock;”         -   Icon 442 for workout support module 142, labeled “Workout             Support;”         -   Icon 444 for notes module 153, labeled “Notes;” and         -   Icon 446 for a settings application or module, which             provides access to settings for device 100 and its various             applications 136.

It should be noted that the icon labels illustrated in FIG. 4A are merely exemplary. For example, icon 422 for video and music player module 152 are labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon.

FIG. 4B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from the display 450 (e.g., touch screen display 112). Device 300 also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors 357) for detecting intensity of contacts on touch-sensitive surface 451 and/or one or more tactile output generators 359 for generating tactile outputs for a user of device 300.

Although some of the examples which follow will be given with reference to inputs on touch screen display 112 (where the touch sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in FIG. 4B. In some embodiments the touch sensitive surface (e.g., 451 in FIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) that corresponds to a primary axis (e.g., 453 in FIG. 4B) on the display (e.g., 450). In accordance with these embodiments, the device detects contacts (e.g., 460 and 462 in FIG. 4B) with the touch-sensitive surface 451 at locations that correspond to respective locations on the display (e.g., in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470). In this way, user inputs (e.g., contacts 460 and 462, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 451 in FIG. 4B) are used by the device to manipulate the user interface on the display (e.g., 450 in FIG. 4B) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein.

Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously.

As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector,” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad 355 in FIG. 3 or touch-sensitive surface 451 in FIG. 4B) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch-screen display (e.g., touch-sensitive display system 112 in FIG. 1A or touch screen 112 in FIG. 4A) that enables direct interaction with user interface elements on the touch-screen display, a detected contact on the touch-screen acts as a “focus selector,” so that when an input (e.g., a press input by the contact) is detected on the touch-screen display at a location of a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch-screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch-screen display) that is controlled by the user so as to communicate the user's intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device).

The user interface figures described below include various intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to one or more intensity thresholds (e.g., a contact detection intensity threshold IT₀, a light press intensity threshold IT_(L), a deep press intensity threshold IT_(D), and/or one or more other intensity thresholds). This intensity diagram is typically not part of the displayed user interface, but is provided to aid in the interpretation of the figures. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with an intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold IT₀ below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures.

An increase of intensity of the contact from an intensity below the light press intensity threshold IT_(L) to an intensity between the light press intensity threshold IT_(L) and the deep press intensity threshold IT_(D) is sometimes referred to as a “light press” input. An increase of intensity of the contact from an intensity below the deep press intensity threshold IT_(D) to an intensity above the deep press intensity threshold IT_(D) is sometimes referred to as a “deep press” input. An increase of intensity of the contact from an intensity below the contact-detection intensity threshold IT₀ to an intensity between the contact-detection intensity threshold IT₀ and the light press intensity threshold IT_(L) is sometimes referred to as detecting the contact on the touch-surface. A decrease of intensity of the contact from an intensity above the contact-detection intensity threshold IT₀ to an intensity below the contact intensity threshold IT₀ is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments IT₀ is zero. In some embodiments IT₀ is greater than zero. In some illustrations a shaded circle or oval is used to represent intensity of a contact on the touch-sensitive surface. In some illustrations a circle or oval without shading is used represent a respective contact on the touch-sensitive surface without specifying the intensity of the respective contact.

In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input).

In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90% or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances).

For ease of explanation, the description of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold.

User Interfaces and Associated Processes Previewing and Selecting Content Items

Many electronic devices have graphical user interfaces that include various content fields and a multitude of content items. For example, photo album software allows a user to arrange and customize pictures to be displayed or printed at a later time. In this example, customizing the pictures optionally includes selecting between various pictures to display in a particular frame. Some methods of selecting between various pictures require multiple sequential inputs performed with different contacts to navigate through pop-up or drop-down menus, which can take a long time and be confusing to a user. There is a need to provide a fast, efficient, and convenient way for previewing and selecting content items corresponding to a content field that reduce or eliminate separate steps or inputs or user interfaces that a user would otherwise navigate through to perform a content selection operation. The embodiments below improve on the existing methods by reducing the cognitive burden on a user and produce a more efficient human-machine interface.

FIGS. 5A-5N illustrate exemplary user interfaces for previewing and selecting content items corresponding to a content field in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes described below with reference to FIGS. 6A-6C. FIGS. 5A-5L include intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to a plurality of intensity thresholds including a respective threshold (e.g., “IT_(L)”). In some embodiments, operations similar to those described below with reference to IT_(L) are performed with reference to a different intensity threshold (e.g., “IT_(D)”).

FIGS. 5A-5F illustrate an example of previewing and selecting electronic messages corresponding to a reading pane. FIGS. 5A-5F show user interface 18002 including email application 18004 with reading pane 18006 displayed on display 450 of a device (e.g., device 300, FIG. 3). FIGS. 5A-5F also show contact 18010 on touch-sensitive surface 451 and intensity of contact 18010. In accordance with some embodiments, FIGS. 5A-5F further illustrate a displayed representation of focus selector (e.g., cursor 18008). FIG. 5B shows intensity of contact 18010 above IT_(L) while cursor 18008 is over reading pane 18006. FIG. 5B also shows content menu 18012 including multiple options that correspond to individual emails. FIG. 5C shows movement of contact 18010 and corresponding movement of cursor 18008 to a position over a representation of email 1 in content menu 18012. FIG. 5D shows cursor 18008 over the representation of email 1 in content menu 18012 and email 1 preview 18014 displayed in reading pane 18006. FIGS. 5D-5E shows intensity of contact 18010 increasing from an intensity below IT_(D) in FIG. 5D to an intensity above IT_(D) in FIG. 5E while cursor 18008 is over the representation of email 1 in content menu 18012. FIG. 5E also shows email 1 preview 18014 expanding in reading pane 18006. FIG. 5F shows email 18016 in reading pane 18006. In some embodiments, the email is inserted into reading pane 18006 when the intensity of contact 18010 increases above IT_(D). In some embodiments, the email is inserted into reading pane 18006 when, after the intensity of contact 18010 reached an intensity above IT_(D), the intensity of contact 18010 is reduced below a hysteresis intensity threshold associated with (and below) IT_(D).

In some embodiments, the device is an electronic device with a separate display (e.g., display 450) and a separate touch-sensitive surface (e.g., touch-sensitive surface 451). In some embodiments, the device is portable multifunction device 100, the display is touch-sensitive display system 112, and the touch-sensitive surface includes contact intensity sensors 165 on the display (FIG. 1A). For convenience of explanation, the embodiments described with reference to FIGS. 5A-5F will be discussed with reference to display 450 and a separate touch-sensitive surface 451. However, analogous operations are, optionally, performed on a device with a touch-sensitive display system 112 in response to detecting the contacts described in FIGS. 5A-5F on the touch-sensitive display system 112 while displaying the user interfaces shown in FIGS. 5A-5F on the touch-sensitive display system 112; in such embodiments, the focus selector is, optionally: a respective contact, a representative point corresponding to a contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112, in place of cursor 18008.

FIGS. 5G-5N illustrate an example of previewing and selecting pictures corresponding to a picture frame. FIGS. 5G-5N show touch screen 112 on portable multifunction device 100. FIGS. 5G-5N further show picture editing application 18020 including frame 18022 displayed on touch screen 112. FIG. 5G shows contact 18024 with intensity below IT_(L) detected over frame 18022. FIGS. 5G-5H show an intensity of contact 18024 increasing from an intensity below IT_(L) in FIG. 5G to an intensity above IT_(L) in FIG. 5H and content menu 18026 including picture representations 18028 being displayed in response to detecting the increase in intensity of contact 18024. FIGS. 5I-5J show movement of contact 18024 over picture representation 18028-2 in content menu 18026.

FIG. 5J shows contact 18024 over picture representation 18028-2 and picture 2 preview 18030 in frame 18022. FIGS. 5K-5L shows movement of contact 18024 over picture representation 18028-1 in content menu 18026. FIG. 5L shows contact 18024 over picture representation 18028-1 and picture 1 preview 18032 in frame 18022. FIG. 5M shows liftoff of contact 18024 (e.g., a decrease in intensity of contact 18024 from an intensity above IT₀ to an intensity below IT₀) while over picture representation 18028-1. FIG. 5M also shows picture 1 preview 18032 expanding in frame 18022. FIG. 5N shows picture 18034 in frame 18022.

FIGS. 6A-6C are flow diagrams illustrating method 18100 of previewing and selecting content items corresponding to a content field in accordance with some embodiments. Method 18100 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 18100 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, method 18100 provides an intuitive way to preview and select content items corresponding to a content field in accordance with some embodiments. The method reduces the cognitive burden on a user when navigating user interface hierarchies, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to previewing and selecting content items faster and more efficiently conserves power and increases the time between battery charges.

The device displays (18102) a content field (e.g., a frame for an image or picture, a text box, or a field for entering a numerical value) on the display. For example, the device in FIG. 5A displays reading pane 18006 in email application 18004. As another example, the device in FIG. 5G displays a frame 18022 in a picture editing application 18020.

The device detects (18104) a contact on the touch-sensitive surface, where the contact corresponds to a focus selector on the display. For example, the device in FIG. 5A detects contact 18010 on touch-sensitive surface 451 corresponding to cursor 18008 on display 450. As another example, the device in FIG. 5G detects a contact 18024 on touch screen 112.

While continuously detecting (18106) the contact on the touch-sensitive surface: the device detects (18108) a press input that includes an increase in intensity of the contact above a respective intensity threshold (e.g., IT_(L)) while the focus selector is over the content field. In some embodiments, the respective intensity threshold is an intensity threshold that is higher than an input-detection intensity threshold at which the contact is initially detected. For example, in FIGS. 5A-5B the device detects the intensity of contact 18010 increasing above IT_(L) while cursor 18008 is over reading pane 18006. As another example, in FIGS. 5G-5H, the device detects the intensity of contact 18024 increasing from an intensity below IT_(L) to an intensity above IT_(L).

In response to detecting the press input, the device displays (18110) a content menu that includes representations of a plurality of options that correspond to content items. For example, the device in FIG. 5B displays content menu 18012 including a multitude of email representations. As another example, in FIG. 5H, the device displays content menu 18026 including a plurality of picture representations 18028.

While displaying the content menu, the device detects (18112) movement of the contact that corresponds to movement of the focus selector over a representation of a first content item in the content menu. For example, the device in FIGS. 5C-5D detects movement of contact 18010 over the representation of email 1 in content menu 18012. As another example, in FIGS. 5I-5L, the device detects movement of contact 18024 over picture 1 representation 18028-1.

In response to the focus selector being over the representation of the first content item in the content menu, the device displays (18114) a preview (e.g., a transient preview) of the first content item in the content field. For example, FIG. 5D shows cursor 18008 over email 1 representation in content menu 18012 and the device in FIG. 5D displays email 1 preview 18014 in reading pane 18006. As another example, in FIG. 5L, the device displays picture 1 preview 18032 in frame 18022.

In some embodiments, while continuously detecting the contact, after detecting the first press input and before detecting movement of the contact that corresponds to movement of the focus selector over the representation of the first content item in the content menu: the device detects (18116) movement of the contact that corresponds to movement of the focus selector over one or more other representations of corresponding other content items besides the first content item and, in response to detecting movement of the contact that corresponds to movement of the focus selector over a representation of one of the other content items, the device displays a preview (e.g., a transient preview) of the corresponding other content item in the content field (e.g., without permanently inserting the other content item in the content field). For example, portable multifunction device 100 in FIGS. 5I-5J detects movement of contact 18024 over picture representation 18028-2 in content menu 18026 and (in FIG. 5J) displays picture 2 preview 18030 in frame 18022 (in FIG. 5J). In accordance with these embodiments, portable multifunction device 100 detects movement of contact 18024 over picture representation 18028-2 in FIGS. 5I-5J before detecting movement of contact 18024 over picture representation 18028-1 in FIGS. 5K-5L.

The device detects (18118) a confirmation input while the focus selector associated with the contact is over the representation of the first content item in the content menu. For example, the device in FIGS. 5D-5E detects an increase in intensity of contact 18010 from an intensity below IT_(D) in FIG. 5D to an intensity above IT_(D) in FIG. 5E while cursor 18008 is over the email 1 representation in content menu 18012. As another example, in FIGS. 5L-5M, the device detects a liftoff of contact 18024 from touch screen 112.

In some embodiments, the press input, the movement of the contact, and the confirmation input are performed (18120) with a single continuous contact (e.g., as part of a single gesture). In accordance with these embodiments, for example, the device in FIGS. 5A-5F detects an increase in intensity of contact 18010 above IT_(L) in FIG. 5B, movement of contact 18010 in FIG. 5C, and an increase in intensity of contact 18010 above IT_(D) in FIG. 5E as part of a single, continuous contact (e.g., a single gesture). As another example, contact 18024 is continuously detected throughout FIGS. 5G-5L.

In some embodiments, detecting the confirmation input includes (18122) detecting liftoff of the contact from the touch-sensitive surface. For example, portable multifunction device 100 in FIGS. 5L-5M detects liftoff of contact 18024 and, in response, in FIG. 5N inserts picture 18034 in frame 18022.

In some embodiments, detecting the confirmation input includes (18124) detecting an increase in intensity of the contact above an insertion intensity threshold (e.g., the respective intensity threshold or an intensity threshold above the respective intensity threshold) while the focus selector is over the representation of the first content item in the content menu. For example, the device in FIGS. 5D-5E detects an increase in intensity of contact 18010 from an intensity below IT_(D) in FIG. 5D to an intensity above IT_(D) in FIG. 5E and, in response, in FIG. 5F inserts email 18016 in reading pane 18006.

In response to detecting the confirmation input, the device inserts (18126) the first content item into the content field. For example, the device in FIG. 5N inserts picture 18034 in frame 18022. As another example, in FIG. 5F, the device inserts email 1 into reading pane 18006. In some implementations, inserting the first content item into the content field enables further operations to be performed on the first content item, including at least one operation not available for use with the corresponding preview. In some implementations, a preview is transient and either not operative or less fully operative compared with the respective content item inserted in the content field. In some implementations, inserting the first content item into the content field means non-transiently associating the first content item with the content field and displaying a representation of the first content item in the content field. For example, in accordance with some implementations, a photo application displays a preview of a photo only when the focus selector is over a corresponding photo representation in a content menu. In this example, if no confirmation input is detected, then the photo preview does not continue when the focus selector stops focusing on the corresponding photo representation in the content menu (e.g., when a cursor or contact moves away from a region corresponding to a representation of the content such as a photo preview). Conversely, in this example, if a confirmation input is detected, then the photo is associated with the photo application and will continue to display after the focus selector stops focusing on the corresponding photo representation in the content menu (e.g., when the cursor or contact moves away from the region corresponding to the representation of the content such as a photo preview). Optionally, in this example, additional photo editing options are available to the user after a confirmation input is detected.

In some embodiments, the content items are images and the content field is (18128) an image frame in an electronic document editing application. For example, in accordance with these embodiments, FIGS. 5G-5N show picture editing application 18020 including frame 18022 and content menu 18026 includes picture representations 18028. FIG. 5N further shows picture 18034 in frame 18022. In some embodiments, the content items are electronic messages and the content field is (18130) a reading pane in an electronic message application. For example, in accordance with these embodiments, FIGS. 5A-5F show email application 18004 including reading pane 18006 and content menu 18012 includes email representations. FIG. 5F further shows email 18016 in reading pane 18006.

It should be understood that the particular order in which the operations in FIGS. 6A-6C have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) are also applicable in an analogous manner to method 18100 described above with respect to FIGS. 6A-6C. For example, the contacts, gestures, intensity thresholds, focus selectors, content fields, content menus, and content items described above with reference to method 18100 optionally have one or more of the characteristics of the contacts, gestures, intensity thresholds, focus selectors, content fields, content menus, and content items described herein with reference to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments). For brevity, these details are not repeated here.

In accordance with some embodiments, FIG. 7 shows a functional block diagram of an electronic device 18200 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in FIG. 7 are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

As shown in FIG. 7, electronic device 18200 includes display unit 18202 configured to display a content field, touch-sensitive surface unit 18204 configured to receive user contacts, one or more sensor units 18205 configured to detect intensity of contacts with the touch-sensitive surface unit, and processing unit 18206 coupled to display unit 18202, touch-sensitive surface unit 18204, and sensor units 18205. In some embodiments, processing unit 18206 includes detecting unit 18208, display enabling unit 18210, and inserting unit 18212.

Processing unit 18206 is configured to detect (e.g., with detecting unit 18208) a contact on touch-sensitive surface unit 18204, where the contact corresponds to a focus selector on the display unit, and while continuously detecting the contact on touch-sensitive surface unit 18204, detect (e.g., with detecting unit 18208) a press input that includes an increase in intensity of the contact above a respective intensity threshold while the focus selector is over the content field, and in response to detecting the press input, enable display of (e.g., with display enabling unit 18210) a content menu that includes representations of a plurality of options that correspond to content items. Processing unit 18206 is also configured, while continuously detecting the contact on touch-sensitive surface unit 18204, and while displaying the content menu, to detect (e.g., with detecting unit 18208) movement of the contact that corresponds to movement of the focus selector over a representation of a first content item in the content menu, and, in response to the focus selector being over the representation of the first content item in the content menu, enable display of (e.g., with display enabling unit 18210) a preview of the first content item in the content field. Processing unit 18206 is further configured to detect (e.g., with detecting unit 18208) a confirmation input while the focus selector associated with the contact is over the representation of the first content item in the content menu and, in response to detecting the confirmation input, insert (e.g., with inserting unit 18212) the first content item into the content field.

In some embodiments, the press input, the movement of the contact, and the confirmation input are performed with a single continuous contact.

In some embodiments, detecting (e.g., with detecting unit 18208) the confirmation input includes detecting liftoff of the contact from touch-sensitive surface unit 18204.

In some embodiments, detecting (e.g., with detecting unit 18208) the confirmation input includes detecting an increase in intensity of the contact above an insertion intensity threshold while the focus selector is over the representation of the first content item in the content menu.

In some embodiments, processing unit 18206 is further configured to, while continuously detecting the contact, after detecting (e.g., with detecting unit 18208) the first press input and before detecting (e.g., with detecting unit 18208) movement of the contact that corresponds to movement of the focus selector over the representation of the first content item in the content menu, detect (e.g., with detecting unit 18208) movement of the contact that corresponds to movement of the focus selector over one or more other representations of corresponding other content items besides the first content item and, in response to detecting movement of the contact that corresponds to movement of the focus selector over a representation of one of the other content items, enable display of (e.g., with display enabling unit 18210) a preview of the corresponding other content item in the content field.

In some embodiments, the content items are images and the content field is an image frame in an electronic document editing application.

In some embodiments, the content items are electronic messages and the content field is a reading pane in an electronic message application.

The operations in the information processing methods described above are, optionally, implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to FIGS. 1A and 3) or application specific chips.

The operations described above with reference to FIGS. 6A-6C are, optionally, implemented by components depicted in FIGS. 1A-1B or FIG. 7. For example, detection operations 18104, 18108, 18112, and 18118 and inserting operation 18126 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.

Moving and Dropping a User Interface Object

Many electronic devices have graphical user interfaces that allow a user to move a user interface object, such as an icon. In some situations, a user moves a user interface object by selecting it (e.g., making an input with a focus selector over the user interface object) and then making a movement input. Some methods for moving a user interface object make the user move both the focus selector and the user interface object to the target location, and then stop there, before the user can move the focus selector to another user interface object. In the embodiments described below, an improved method for moving a user interface object is achieved. When a user interface object is selected with a focus selector, and the focus selector is moved with a moving contact, the user interface object moves along with the focus selector. At some location during the movement, if the intensity of the contact does not meet certain intensity criteria (e.g., the contact intensity goes below an intensity threshold), the user interface object is dropped at the location. If the intensity of the contact meets the intensity criteria, the focus selector and the user interface object continues moving together. Thus, the user can drag and drop a user interface object at a desired location and keep the focus selector moving (e.g., to another user interface object) without stopping.

FIGS. 8A-8J illustrate exemplary user interfaces for moving and dropping a user interface object in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in FIGS. 9A-9C. FIGS. 8A-8J include intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to a plurality of intensity thresholds including a light press intensity threshold (e.g., “IT_(L)”) and a maintain-object-selection intensity threshold (e.g., “IT₁”). In some embodiments, operations similar to those described below with reference to “IT_(L)” are performed with reference to a different intensity threshold (e.g., “IT_(D)”). In some embodiments, the light press intensity threshold (e.g., “IT_(L)”) is the different from the maintain-object-selection intensity threshold (e.g., “IT₁”), as shown in FIGS. 8A-8J. However, in some embodiments, the light press intensity threshold (e.g., “IT_(L)”) is the same as the maintain-object-selection intensity threshold (e.g., “IT₁”).

In some embodiments, the device is an electronic device with a separate display (e.g., display 450) and a separate touch-sensitive surface (e.g., touch-sensitive surface 451). In some embodiments, the device is portable multifunction device 100, the display is touch-sensitive display system 112, and the touch-sensitive surface includes tactile output generators 167 on the display (FIG. 1A). For convenience of explanation, the embodiments described with reference to FIGS. 8A-8J and FIGS. 9A-9C will be discussed with reference to display 450 and a separate touch-sensitive surface 451, however analogous operations are, optionally, performed on a device with a touch-sensitive display system 112 in response to detecting the contacts described in FIGS. 8A-8J on the touch-sensitive display system 112 while displaying the user interfaces shown in FIGS. 8A-8J on the touch-sensitive display system 112; in such embodiments, the focus selector is, optionally: a respective contact, a representative point corresponding to a contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112, in place of cursor 18310.

FIG. 8A illustrates media (e.g., video, audio) player user interface 18304 displayed on display 450 (e.g., display 340, touch screen 112) of a device (e.g., device 300, 100). Media player user interface 18304 is, optionally, a user interface for a media player application (e.g., a standalone application, web-based application). User interface 18304 includes slider 18306 with thumb 18308. Slider 18306 is, optionally, a playback progress bar or a volume control.

Cursor 18310 is also displayed on display 450. Cursor 18310 is an example of a focus selector. A user is, optionally, enabled to move cursor 18310 across display 450 by making a corresponding input on touch-sensitive surface 451 or another input device (e.g., a mouse).

Cursor 18310 is, optionally, used to control movement of thumb 18308 along slider 18306. In some embodiments, cursor 18310 is associated with control of movement of thumb 18308 when cursor 18310 is positioned over thumb 18308 and a contact (e.g., contact 18312) is detected on touch-sensitive surface 451 of the device and contact 18312 has an intensity above the light press intensity threshold. In response to the detection of contact 18312 on touch-sensitive surface 451 while cursor 18310 is located over thumb 18308, thumb 18308 is selected and ready to be moved, as shown in FIG. 8B. Thumb 18308 is moved along slider 18306 by moving contact 18312 on touch-sensitive surface 451, e.g., with movement 18314, while thumb 18308 is selected, as shown in FIGS. 8B-8C.

Movement of thumb 18308 is constrained to be along a predefined path defined by slider 18306. The predefined path defined by slider 18306 runs along the length axis of slider 18306. Thus, thumb 18308 is moved along slider 18306 in accordance with the component of movement 18314 that is parallel to the length axis of slider 18306. The component of movement 18314 that is perpendicular to the length axis of slider 18306 moves cursor 18310 but does not affect the movement of thumb 18308. For example, if contact 18312 is moved diagonally, cursor 18310 would move diagonally in accordance with the diagonal movement of contact 18312, including away from thumb 18308, but thumb 18308 would continue to move along the length axis of slider 18306 in accordance with the component of the movement of contact 18312 that is parallel to the length axis of slider 18306. While the examples described with reference to FIGS. 8A-8J are described with reference to a user interface object (e.g., thumb 18308) that is constrained to a predefined path (e.g., slider 18306), in some embodiments, analogous operations are performed with reference to an object (e.g., a shape in a drawing program, an icon on a desktop or the like) that is not constrained to a predefined path.

In FIGS. 8A-8B, the device detects movement 18311 of contact 18312 across the touch-sensitive surface 451 and, in response to detecting the movement, moves 18307 of cursor 18310 to a location over thumb 18308 on display 450.

In FIGS. 8B-8C, while cursor 18310 is located over thumb 18308, the device detects an increase in intensity of contact 18312 from an intensity below the light press intensity threshold (e.g., “IT_(L)”) in FIG. 8B to an intensity above the light press intensity threshold (e.g., “IT_(L)”) in FIG. 8C. In response to detecting the increase in intensity of contact 18312 shown in FIGS. 8B-8C, the device selects (or “picks up”) thumb 18308. In FIGS. 8C-8D, while thumb 18308 is selected, the device detects movement 18314 of contact 18312 to the right on touch-sensitive surface 451, and in response to detecting the movement, moves 18316 cursor 18310 and thumb 18308 to the right along the predefined path corresponding to slider 18306.

In FIGS. 8D-8E, the device continues to detect that the intensity of contact 18312 is maintained over the maintain-object-selection intensity threshold (e.g., “IT₁”) and thus, in response to detecting movement 18318 of contact 18312 further to the right on touch-sensitive surface 451, the device continues to move 18320 cursor 18310 and thumb 18308 to the right along the predefined path corresponding to slider 18306. In FIG. 8F, the device detects liftoff of contact 18312 from touch-sensitive surface 451 and thus does not move cursor 18310 or thumb 18308, as contact 18312 is no longer detected on the touch-sensitive surface.

Similarly, in FIGS. 8B and 8G, while cursor 18310 is located over thumb 18308, the device detects an increase in intensity of contact 18312 from an intensity below the light press intensity threshold (e.g., “IT_(L)”) in FIG. 8B to an intensity above the light press intensity threshold (e.g., “IT_(L)”) in FIG. 8G. In response to detecting the increase in intensity of contact 18312 shown in FIGS. 8B and 8G, the device selects (or “picks up”) thumb 18308. In FIGS. 8G-8H, while thumb 18308 is selected, the device detects movement 18322 of contact 18312 to the right on touch-sensitive surface 451, and in response to detecting the movement, moves 18324 cursor 18310 and thumb 18308 to the right along the predefined path corresponding to slider 18306. Note that the movement of cursor 18310 and thumb 18308 in FIGS. 8G-8H is analogous to the movement of cursor 18310 and thumb 18308 in FIGS. 8C-8D.

However, in FIGS. 8H-8I, the device detects a decrease in intensity of contact 18312 from an intensity above the maintain-object-selection intensity threshold (e.g., “IT₁”) in FIG. 8H to an intensity below the maintain-object-selection intensity threshold (e.g., “IT₁”), or an associated hysteresis intensity threshold, in FIG. 8I. In response to detecting the decrease in intensity of contact 18312 shown in FIGS. 8H-8I, the device deselects (or “drops”) thumb 18308.

Subsequently, in FIGS. 8I-8J, in response to detecting movement 18326 of contact 18312 further to the right on touch-sensitive surface 451, the device continues to move 18328 cursor 18310 to the right on display 450, however, because the device detected a decrease in intensity of contact 18310 below the maintain-object-selection intensity threshold (e.g., “IT₁”) in FIGS. 8H-8I, the device does not move thumb 18308 along the predefined path corresponding to slider 18306 (e.g., because the thumb 18308 was “dropped”). Thus, in FIGS. 8G-8J, the user is able to deselect a selected user interface object without lifting contact 18312 off of touch-sensitive surface 451, which improves the efficiency of the user's interaction with the device, by reducing the number of liftoff operations that the user has to perform.

After the device has deselected (e.g., dropped) thumb 18308, as shown in FIGS. 8I-8J, the user is enabled to select a different user interface object by moving cursor 18310 over the different user interface object and increasing the intensity of contact 18312 over the light press intensity threshold (optionally without lifting contact 18312 off of touch-sensitive surface 451) while cursor 18310 is over the different user interface object.

FIGS. 9A-9C are flow diagrams illustrating a method 18400 of moving and dropping a user interface object in accordance with some embodiments. The method 18400 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 18400 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, the method 18400 provides an intuitive way to move and drop a user interface object. The method reduces the cognitive burden on a user when moving and dropping a user interface object, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to move and drop a user interface object faster and more efficiently conserves power and increases the time between battery charges.

The device detects (18402) a contact (e.g., a finger contact) with the touch-sensitive surface, where the contact is associated with a focus selector (e.g., cursor 18310 or a contact on a touch screen) that controls movement of a respective user interface object that is currently selected. The user interface object is, optionally, a thumb or handle on a slider (e.g., thumb 18308) or a free-moving user interface object. For example, in FIG. 8B, the device detects, on touch-sensitive surface 451, contact 18312, which is associated with cursor 18310 that controls movement of selected thumb 18308.

While continuously detecting (18404) the contact on the touch-sensitive surface, the device detects (18406) first movement of the contact across the touch-sensitive surface corresponding to movement of the focus selector toward a respective location (e.g., the respective location is a location where the user will attempt to “drop” the object). As shown in FIGS. 8C-8D, for example, the device detects movement 18314 of contact 18312 across touch-sensitive surface 451. Similarly, in FIGS. 8G-8H, the device detects movement 18322 of contact 18312 across touch-sensitive surface 451. Movement 18314 (or movement 18322) corresponds to movement of cursor 18310 toward a respective location (e.g., a target location for dropping thumb 18308) on display 450.

In response (18408) to detecting the first movement of the contact across the touch-sensitive surface, the device moves (18410) the focus selector on the display in accordance with the first movement of the contact and moves the respective user interface object in accordance with the movement of the focus selector. The device also determines (18416) an intensity of the contact on the touch-sensitive surface while the focus selector is at the respective location on the display. For example, in response to detecting movement 18314 of contact 18312, the device moves cursor 18310 with movement 18316 in accordance with movement 18314 of contact 18312, and moves thumb 18308 in accordance with the movement of the cursor, as shown in FIG. 8D. The device also determines the intensity of contact 18312 while cursor 18310 is at the target location. In FIG. 8H, in response to detecting movement 18322 of contact 18312, the device moves cursor 18310 with movement 18324 in accordance with movement 18322 of contact 18312, and moves thumb 18308 in accordance with the movement of the cursor. The device also determines the intensity of contact 18312 while cursor 18310 is at the target location.

In some embodiments, movement of the respective user interface object is (18412) constrained to a predefined path in the user interface, and moving the respective user interface object in accordance with movement of the focus selector includes moving the respective user interface object along the predefined path in accordance with a component of motion of the focus selector that corresponds to an allowed direction of motion along the predefined path (e.g., a thumb/handle in a scrubber or slider bar). For example, movement of thumb 18308 is constrained to the path predefined by slider 18306, and thumb 18308 is moved in accordance with the component of the movement of cursor 18310 that is parallel to the path defined by slider 18306 (e.g., the horizontal component of the movement of cursor 18310, which is parallel to the length axis of slider 18306, as depicted in FIGS. 8B-8C).

In some embodiments, the respective user interface object has (18414) a two dimensional range of motion, and moving the respective user interface object in accordance with movement of the focus selector includes moving the respective user interface object to a location at or adjacent to the focus selector on the display (e.g., the respective user interface object is a document icon that can be moved laterally on the display in a two dimensional plane and is not constrained to a predefined path such as a scrubber or a slider bar).

The device detects (18418) second movement of the contact across the touch-sensitive surface that corresponds to movement of the focus selector away from the respective location. For example, in FIGS. 8D-8E, the device detects movement 18318 of contact 18312, which corresponds to movement of cursor 18310 away from the target location. In FIGS. 8I-8J, the device detects movement 18326 of contact 18312, which corresponds to movement of cursor 18310 away from the target location.

In response (18420) to detecting the second movement of the contact across the touch-sensitive surface, in accordance with a determination that the contact meets respective intensity criteria, the device moves (18422) the focus selector and the user interface object in accordance with the second movement of the contact across the touch-sensitive surface (e.g., detecting an unsuccessful user interface object drop). For example, in FIGS. 8D-8E, in response to detecting movement 18318 of contact 18312 that meets the intensity criteria (e.g., because the intensity of contact 18312 is above IT₁), the device moves cursor 18310 with movement 18318 and moves 18320 thumb 18308 in accordance with movement of cursor 18310, as thumb 18308 is still selected. In some embodiments, the respective intensity criteria include a respective intensity threshold (e.g., IT₁ or IT_(L)), and the contact meets the respective intensity criteria when the intensity of the contact is above the respective intensity threshold (18424). For example, contact 18312 meets the intensity criteria in FIG. 8D, because the intensity of the contact is above the maintain-object-selection intensity threshold (e.g., “IT₁”).

In response (18420) to detecting the second movement of the contact across the touch-sensitive surface, in accordance with a determination that the contact does not meet the respective intensity criteria, the device moves (18426) the focus selector in accordance with the second movement of the contact across the touch-sensitive surface without moving the user interface object (e.g., detecting a successful user interface object drop). For example, in FIGS. 8I-8J, in response to detecting movement 18318 of contact 18312 that does not meet the intensity criteria (e.g., because the intensity of contact 18312 is below IT₁), the device moves cursor 18310 with movement 18328 in accordance with movement 18318 but does not move thumb 18308, as thumb 18308 is not selected. In some embodiments, the respective intensity criteria include a maintain—object-selection intensity threshold (e.g., “IT₁”) such that when the contact has an intensity above the maintain—object-selection intensity threshold (e.g., “IT₁”), the object remains selected. Conversely, when the contact has an intensity below the maintain—object-selection intensity threshold (e.g., “IT₁”), the object is dropped and ceases to be selected.

In some embodiments, the respective intensity criteria include a respective intensity threshold, and the contact does not meet (18428) the respective intensity criteria when the intensity of the contact is below the respective intensity threshold (e.g., the contact is determined not to meet the respective intensity criteria when the contact is below the IT₁ for any amount of time). For example, contact 18312 does not meet the intensity criteria if the intensity of the contact is below an intensity threshold (e.g., maintain-object-selection intensity threshold IT₁). In some embodiments, the respective intensity criteria include a respective intensity threshold, and the contact does not meet (18430) the respective intensity criteria when the intensity of the contact is below the respective intensity threshold for more than a predefined period of time (e.g., the contact is determined not to meet the respective intensity criteria when the contact is below the respective intensity threshold for at least 0.05, 0.1, 0.2, 0.5 seconds, or some other reasonable delay threshold). For example, contact 18312 does not meet the intensity criteria if the intensity of the contact is below the maintain-object-selection intensity threshold (e.g., “IT₁”) for at least the predefined period of time.

In some embodiments, the respective intensity criteria include a respective intensity threshold (18432). In some embodiments, the respective intensity threshold is (18434) a predefined intensity threshold (e.g., the user interface object is “dropped” if/when the intensity of the contact drops below a pre-set intensity threshold). In some embodiments, the respective intensity threshold is (18436) based on a percentage of a maximum intensity of the contact detected during the gesture. For example, the user interface object (e.g., thumb 18308) is “dropped” if/when the intensity of the contact (e.g., contact 18312) drops by 90% of a maximum intensity of the contact during the gesture. In some embodiments, the respective intensity threshold corresponds (18438) to an intensity measurement that is greater than a nominal intensity measurement (e.g., contact detection intensity threshold IT₀) that indicates that the contact (e.g., contact 18312) is in contact with the touch-sensitive surface 451).

In some embodiments, when the one or more sensors used to detect contact intensity (e.g., “intensity sensors”) are capable of measuring 4 or more quantized values of intensity, where N is the lowest quantized value of intensity (e.g., the value of intensity that corresponds to the presence of a contact on the touch-sensitive surface), the respective intensity threshold is at least one level above N. For example if there are 4 quantized values of intensity and 1 is the lowest level, then the respective intensity threshold is 2 (or some other level greater than 2). As another example, if there are 256 quantized values of intensity and 1 is the lowest level, then the respective intensity threshold is 2 (or some other level greater than 2, such as 5, 10 or 15). For example in FIG. 8A, the device can detect and differentiate between at least a first intensity between IT₀ and IT₁, a second intensity between IT₁ and IT_(L), a third intensity between IT_(L) and IT_(D) and a fourth intensity above IT_(D).

In some embodiments, while moving the respective user interface object in accordance with the second movement of the contact across the touch-sensitive surface, the device detects (18440) a liftoff of the contact from the touch-sensitive surface. In response to detecting the liftoff, the device ceases (18442) to move the respective user interface object on the display in accordance with the second movement of the contact (e.g., when the contact ceases to be detected, the device “drops” the respective user interface object, which results in movement of the respective user interface object across the display ceasing, either immediately or gradually). For example, in FIG. 8F, while the device is moving thumb 18308 in accordance with movement 18318 of contact 18312 (as shown in FIGS. 8C-8E), contact 18312 is lifted off touch-sensitive surface 451, and in response to detecting the liftoff, the device stops moving thumb 18308.

As described, above, steps 18406 through 18438 are, optionally, performed while the contact is continuously detected on the touch-sensitive surface. That continuously detected contact is, optionally, lifted off, and that liftoff is detected in step 18440. In response to detection of that liftoff, the device ceases to move the respective user interface object on the display in accordance with the second movement of the contact. Thus, in some embodiments, the object can be dropped either by lifting a contact associated with the focus selector or by reducing the intensity of the contact associated with the focus selector so that the contact does not meet the contact intensity criteria.

It should be understood that the particular order in which the operations in FIGS. 9A-9C have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) are also applicable in an analogous manner to method 18400 described above with respect to FIGS. 9A-9C. For example, the contacts, user interface objects, intensity thresholds, and focus selectors described above with reference to method 18400 optionally has one or more of the characteristics of the contacts, user interface objects, intensity thresholds, and focus selectors described herein with reference to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments). For brevity, these details are not repeated here.

In accordance with some embodiments, FIG. 10 shows a functional block diagram of an electronic device 18500 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in FIG. 10 are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

As shown in FIG. 10, an electronic device 18500 includes a display unit 18502; a touch-sensitive surface unit 18504 configured to receive contacts; one or more sensor units 18505 configured to detect intensity of contacts with the touch-sensitive surface unit 18504; and a processing unit 18506 coupled to the display unit 18502, the touch-sensitive surface unit 18504, and the sensor units 18505. In some embodiments, the processing unit 18506 includes a detecting unit 18508, a moving unit 18510, a determining unit 18512, and a ceasing unit 18514.

The processing unit 18506 is configured to: detect a contact with the touch-sensitive surface unit 18504, wherein the contact is associated with a focus selector that controls movement of a respective user interface object that is currently selected (e.g., with the detecting unit 18508); and while continuously detecting the contact on the touch-sensitive surface unit 18504: detect first movement of the contact across the touch-sensitive surface unit 18504 corresponding to movement of the focus selector toward a respective location (e.g., with the detecting unit 18508); in response to detecting the first movement of the contact across the touch-sensitive surface unit 18504: move the focus selector on the display unit 18502 in accordance with the first movement of the contact and move the respective user interface object in accordance with the movement of the focus selector (e.g., with the moving unit 18510), and determine an intensity of the contact on the touch-sensitive surface unit 18504 while the focus selector is at the respective location on the display unit 18502 (e.g., with the determining unit 18512); detect second movement of the contact across the touch-sensitive surface unit 18504 that corresponds to movement of the focus selector away from the respective location (e.g., with the detecting unit 18508); and in response to detecting the second movement of the contact across the touch-sensitive surface unit 18504: in accordance with a determination that the contact meets respective intensity criteria, move the focus selector and the user interface object in accordance with the second movement of the contact across the touch-sensitive surface unit 18504 (e.g., with the moving unit 18510); and in accordance with a determination that the contact does not meet the respective intensity criteria, move the focus selector in accordance with the second movement of the contact across the touch-sensitive surface unit 18504 without moving the user interface object (e.g., with the moving unit 18510).

In some embodiments, movement of the respective user interface object is constrained to a predefined path in the user interface, and moving the respective user interface object in accordance with movement of the focus selector includes moving the respective user interface object along the predefined path in accordance with a component of motion of the focus selector that corresponds to an allowed direction of motion along the predefined path.

In some embodiments, the respective user interface object has a two dimensional range of motion; and moving the respective user interface object in accordance with movement of the focus selector includes moving the respective user interface object to a location at or adjacent to the focus selector on the display unit 18502.

In some embodiments, the respective intensity criteria include a respective intensity threshold, and the contact meets the respective intensity criteria when the intensity of the contact is above the respective intensity threshold.

In some embodiments, the respective intensity criteria include a respective intensity threshold, and the contact does not meet the respective intensity criteria when the intensity of the contact is below the respective intensity threshold.

In some embodiments, the respective intensity criteria include a respective intensity threshold, and the contact does not meet the respective intensity criteria when the intensity of the contact is below the respective intensity threshold for more than a predefined period of time.

In some embodiments, the respective intensity threshold is a predefined intensity threshold.

In some embodiments, the respective intensity threshold is based on a percentage of a maximum intensity of the contact detected during the gesture.

In some embodiments, the respective intensity threshold corresponds to an intensity measurement that is greater than a nominal intensity measurement that indicates that the contact is in contact with the touch-sensitive surface unit 18504.

In some embodiments, the processing unit 18506 is configured to: while moving the respective user interface object in accordance with the second movement of the contact across the touch-sensitive surface unit 18504, detect a liftoff of the contact from the touch-sensitive surface unit 18504 (e.g., with the detecting unit 18508); and in response to detecting the liftoff, cease to move the respective user interface object on the display unit 18502 in accordance with the second movement of the contact (e.g., with the ceasing unit 18514).

The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to FIGS. 1A and 3) or application specific chips.

The operations described above with reference to FIGS. 9A-9C are, optionally, implemented by components depicted in FIGS. 1A-1B or FIG. 10. For example, detection operations 18402, 18406, and 18418, moving operations 18410, 18422, and 18426, and determining operation 18416 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.

Performing an Operation in Accordance with a Selected Mode of Operation

Many electronic devices have user interfaces in which multiple operations are, optionally, performed with a same type of gesture. When this gesture overloading happens within the same application, the different operations are typically associated with different modes of operation. In some methods, a user can switch between modes of operation by selecting a different mode from a menu of options or making a second contact in addition to the gesture for activating the operation. The embodiments described below improve on these methods. An operation is activated by a sequence of inputs made with a continuous contact with the touch-sensitive surface. The sequence of inputs includes increasing the intensity of the contact and moving the contact after the intensity increase. If the intensity of the contact is increased above a certain threshold, the operation that is activated is based on a different mode of operation than if the intensity is not increased above the threshold. Thus, the user can switch modes of operation smoothly, without making additional inputs, such as going through a menu or making an additional contact.

FIGS. 11A-11W illustrate exemplary user interfaces for performing an operation in accordance with a selected mode of operation in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in FIGS. 12A-12D. FIGS. 11A-11W include intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to a plurality of intensity thresholds including a mode-selection intensity threshold (e.g., “IT_(D)”), a light press intensity threshold (e.g., “IT_(L)”), and an operation-cancellation threshold (e.g., “IT₁”).

In some embodiments, the device is an electronic device with a separate display (e.g., display 450) and a separate touch-sensitive surface (e.g., touch-sensitive surface 451). In some embodiments, the device is portable multifunction device 100, the display is touch-sensitive display system 112, and the touch-sensitive surface includes tactile output generators 167 on the display (FIG. 1A). For convenience of explanation, the embodiments described with reference to FIGS. 11A-11W and FIGS. 12A-12D will be discussed with reference to display 450 and a separate touch-sensitive surface 451, however analogous operations are, optionally, performed on a device with a touch-sensitive display system 112 in response to detecting the contacts described in FIGS. 11A-11W on the touch-sensitive display system 112 while displaying the user interfaces shown in FIGS. 11A-11W on the touch-sensitive display system 112; in such embodiments, the focus selector is, optionally: a respective contact, a representative point corresponding to a contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112, in place of cursor 18605 or cursor 18622.

FIG. 11A illustrates user interface 18604 displayed on display 450 (e.g., display 340, touch screen 112) of a device (e.g., device 300, device 100). In some embodiments, user interface 18604 is a user interface for an application, such as a web browser, a word processing application, or an electronic document application. Document 18606 is displayed in user interface 18604. Document 18606 is, for example, a web page, a word processing document, a text document, a spreadsheet, a presentation, or a drawing. A Document 18606 includes content, such as text 18608. Text 18608 optionally has more text than can be displayed all at once. For example, FIG. 11A shows portion 18608-a of text 18608 displayed in document 18606. A text cursor 18605 is displayed on display 450, text cursor 18605 is an example of a focus selector.

The application includes two or more modes of operation. Inputs to the application (e.g., contacts or gestures detected on touch-sensitive surface 451 of the device) are, optionally, detected in accordance with a mode of operation of the application that is active at the time of detection.

Contact 18610 is detected on touch-sensitive surface 451 at location 18610-a. Contact 18610 is detected as having an intensity between thresholds IT₀ and IT_(L). While contact 18610 is stationary on touch-sensitive surface 451, the intensity of contact 18610 is increased to an intensity between a light press intensity threshold (e.g., “IT_(L)”) and a mode-change intensity threshold (e.g., “IT_(D)”), and the intensity increase is detected, as shown in FIG. 11B. Then, contact 18610, while its intensity is above an operation-cancellation intensity threshold (e.g., “IT₁”) and below the mode-change intensity threshold (e.g., “IT_(D)”), moves 18612 from location 18610-a to location 18610-b (FIG. 11C). In response to detection of the movement of contact 18610, in accordance with the first mode of operation, document 18606 is scrolled, as shown in FIG. 11C, portion 18608-b of text 18608 is displayed in document 18606.

While contact 18610 continues to be detected on touch-sensitive surface 451 the device detects a decrease in intensity of contact 18610 below the operation-cancellation intensity threshold (e.g., “IT₁”), as shown in FIG. 11D and, in response, to detecting the decrease in intensity of contact 18610, the device stops scrolling the document in response to movement of contact 18610. Thus, when contact 18610 continues to move 18614 to location 18610-c (FIG. 11E), the document is not scrolled, as shown in FIG. 11E.

FIG. 11F illustrates user interface 18604, document 18606, and text portion 18608-a and text cursor 18605, displayed on display 450, as in FIG. 11A. Contact 18610 is detected on touch-sensitive surface 451 at location 18610-a in FIG. 11F. Contact 18610 is stationary on touch-sensitive surface 451 and has an intensity between thresholds IT₀ and IT_(L) in FIG. 11F. The intensity of contact 18610 is increased to an intensity above the mode-change intensity threshold (e.g., “IT_(D)”), and the intensity increase is detected, as shown in FIG. 11G. In accordance with the increase in the intensity of contact 18610 above the mode-change intensity threshold (e.g., “IT_(D)”), inputs are detected on touch-sensitive surface 451 in accordance with a second mode of operation that is different from the first mode of operation (e.g., the first mode of operation corresponds to document scrolling and the second mode of operation corresponds to text selection). Thus, in the example shown in FIGS. 11F-11G, the increase in intensity of contact 18610 above the mode-change intensity threshold (e.g., “IT_(D)”) changed the mode of operation to the second mode of operation.

Contact 18610, with the intensity above the mode-change intensity threshold (e.g., “IT_(D)”), moves 18616 from location 18610-a (FIG. 11G) to location 18610-b (FIG. 11H). In response to detection of the movement of contact 18610, in accordance with the second mode of operation, text portion 18617-a of text 18608 is selected, as shown in FIG. 11G. Selected text 18617-a is, optionally, visually emphasized (e.g., with highlighting, with an enclosure, etc.) to indicate its selection.

While contact 18610 continues to be detected on touch-sensitive surface 451 the device detects a decrease in intensity of contact 18610 below the operation-cancellation intensity threshold (e.g., “IT₁”), as shown in FIG. 11I and, in response, to detecting the decrease in intensity of contact 18610, the device continues to select text in the document in response to movement of contact 18610. Thus, when contact 18610 continues to move 18618 to location 18610-c (FIG. 11J), the selection of text continues in accordance with the movement of contact 18610 despite the detection of the decrease in the intensity of contact 18610 in FIG. 11I. For example, text selection 18617 expands to text portion 18617-b in accordance with the movement of contact 18610, as, as shown in FIG. 11J.

In some embodiments, a focus selector (e.g., a text cursor 18605 or a pointer) is displayed on display 450 over document 18606, and text selection in accordance with the second mode of operation (e.g., in response to detection of movement of contact 18610) starts from the location of the focus selector.

Thus, in some embodiments, for the same type of gesture, the mode of operation under which the contact or gesture is detected is different depending on whether the intensity of the contact is exceeded a mode-detection intensity threshold (e.g., “IT_(D)”). If the intensity is not increased above the mode-detection intensity threshold (e.g., “IT_(D)”), an operation is performed in response to detection of the gesture in accordance with a first mode of operation. If the intensity is increased above the mode-detection intensity threshold (e.g., “IT_(D)”), an operation is performed in response to detection of the gesture in accordance with a second mode of operation. In some embodiments, in the second mode of operation, the operation continues despite a decrease in the intensity of the input contact below an operation-cancellation threshold (e.g., “IT₁”) as long as the input contact continues to be detected, whereas in the first mode of operation, the operation is stopped of the intensity decreases below the operation-cancellation threshold (e.g., “IT₁”).

FIG. 11K illustrates user interface 18618 displayed on display 450 of the device. In some embodiments, user interface 18618 is a user interface for an application, such as a drawing application or a presentation application. One or more objects 18620 are displayed in user interface 18618. Objects 18620 are, for example, shapes in a drawing or objects (e.g., graphics, text blocks, etc.) in a presentation document. Objects 18620-1, 18620-2, and 18620-3 are displayed in user interface 18618. A focus selector, such as cursor 18622, is also displayed on display 450, at location in user interface 18618, that is away from objects 18620 in FIG. 11K. In some embodiments, cursor 18622 is a pointer. Inputs are detected on touch-sensitive surface 451 in accordance with a first mode of operation (e.g., the first mode of operation corresponds to dragging and dropping an object and a second mode of operation corresponds to multiple-object selection).

Contact 18624 is detected on touch-sensitive surface 451 at location 18624-a in FIG. 11K. Contact 18624 has an intensity between thresholds IT₀ and IT_(L) in FIG. 11K. Movement 18626 of contact 18624 is detected on touch-sensitive surface 18626. In response to detection of the movement 18626 of contact 18624, cursor 18622 moves in accordance with the movement of contact 18624, as shown in FIG. 11L.

As cursor 18622 moves in accordance with the movement of contact 18624, cursor 18622 moves over object 18620-1 in FIG. 11L. While cursor 18622 is over object 18620-1, the intensity of contact 18624 is increased to an intensity between a light press intensity threshold (e.g., “IT_(L)”) and a mode-change intensity threshold (e.g., “IT_(D)”), as shown in FIG. 11M. In response to detection of the increase in the intensity of contact 18624 in FIG. 11M, in accordance with the first mode of operation, object 18620-1 is selected and “picked up” by cursor 18622, and object 18620-1 moves along with cursor 18622 in accordance with the movement of contact 18624. For example, after the intensity increase shown in FIG. 11M, as contact 18624 continues to move 18628 and 18630 (e.g., from location 18624-b in FIG. 11M to location 18624-c in FIGS. 11N-11O, then to location 18624-d in FIG. 11P), cursor 18622 moves in accordance with the movement of contact 18624 (e.g. from location 18622-b to location 18622-c, then to location 18622-d). In accordance with movement of cursor 18622, object 18620-1 moves across display 450, as shown in FIGS. 11M-11N.

In some embodiments, a tactile output is generated when the intensity of contact 18624 is increased above the light press intensity threshold (e.g., “IT_(L)”), indicating that object 18620-1 has been selected and picked up.

After object 18620-1 is selected and “picked up” in response to the detection of the increase in the intensity of contact 18624 shown in FIG. 11M, the intensity of contact 18624 is, optionally, decreased. For example, while contact 18624 is at location 18624-c in FIGS. 11N-11O, the intensity of contact 18624 is decreased to an intensity between threshold IT₀ and an operation-cancellation intensity threshold (e.g., “IT₁”). In response to detection of the decrease in the intensity of contact 18624 in FIG. 11O, object 18620-1 is dropped and thus ceases to move on display 450 even while contact 18624 continues, as shown in FIG. 11P. Note that, in FIG. 11N, object 18620-1 is still selected even though the intensity of contact 18624 is below IT_(L), because the intensity of contact 18624 is still above IT₁.

In some embodiments, a tactile output is generated when the intensity of contact 18624 is decreased below the operation-cancellation intensity threshold (e.g., “IT₁”), indicating that object 18620-1 has been deselected and dropped.

FIG. 11Q illustrates user interface 18618 and objects 18620-1, 18620-2, and 18620-3 displayed on display 450 of the device, as in FIG. 11K. Objects 18620-1, 18620-2, and 18620-3 are displayed in user interface 18618. Cursor 18622 is also displayed at location in user interface 18618 that is away from objects 18620.

Contact 18624 is detected on touch-sensitive surface 451 at location 18624-a. Contact 18624 has an intensity between thresholds IT₀ and IT_(L). Movement 18632 of contact 18624 is detected on touch-sensitive surface 451. In response to detection of the movement of contact 18624, cursor 18622 moves in accordance with the movement 18632 of contact 18624 in FIGS. 11Q-11R.

As cursor 18622 moves in accordance with the movement of contact 18624, cursor 18622 moves over object 18620-1 in FIG. 11R. While cursor 18622 is over object 18620-1, the intensity of contact 18624 is increased to an intensity above a mode-change intensity threshold (e.g., “IT_(D)”), as shown in FIG. 11S. In response to detection of the increase in the intensity of contact 18624 in FIG. 11S, in accordance with the second mode of operation, object 18620-1 is selected. The increase in the intensity of contact 18624 changed the mode of operation to the second mode. In contrast with the first mode of operation, object 18620-1 is not picked up by cursor 18622; if cursor 18622 continues to move in accordance with movement of contact 18624, object 18620-1 remains at its current location in FIG. 11S.

In some embodiments, a tactile output is generated when the intensity of contact 18624 is increased above light press intensity threshold (e.g., “IT_(L)”) on the way to being increased above the mode-change intensity threshold (e.g., IT_(D)″), indicating that object 18620-1 has been selected.

After object 18620-1 is selected, contact 18624 continues moving 18634 in on touch-sensitive surface 451, to location 18624-c (FIG. 11T). In accordance with the movement of contact 18624, cursor 18622 moves over object 18620-2. In accordance with cursor 18622 moving over object 18620-2 and in accordance with the second mode of operation, object 18620-2 is selected and the selection of object 18620-1 is maintained, so that objects 18620-1 and 18620-2 are selected as shown in FIG. 11T.

In some embodiments, a tactile output is generated when cursor 18622 is moved over object 18620-2 while the intensity of contact 18624 is in the second mode of operation, indicating that object 18620-2 has been selected while maintaining selection of object 18620-1.

After objects 18620-1 and 18620-2 are selected, the intensity of contact 18624 is, optionally, decreased. For example, while contact 18624 is at location 18624-c, the intensity of contact 18624 is decreased to an intensity between threshold IT₀ an operation-cancellation intensity threshold (e.g., “IT₁”). In response to detection of the decrease in the intensity of contact 18624 in FIG. 11U, the selection of objects 18620-1 and 18620-2 is maintained, as shown in FIG. 11U.

In some embodiments, no tactile output is generated when the intensity of contact 18624 is decreased below the operation-cancellation intensity threshold (e.g., “IT₁”) and the selection of objects 18620-1 and 18620-2 is maintained. In some embodiments, the tactile output is not generated whether cursor 18622 is over or proximate to object 18620-1, or over or proximate to object 18620-2.

Contact 18624 moves 18636 from location 18624-c to location 18624-d on touch-sensitive surface 451. In accordance with the movement of contact 18624, cursor 18622 moves so that a selection area encompasses portions of objects 18620-1, 18620-2 and 18620-3, as shown in FIG. 11V. In accordance with cursor 18622 moving over object 18620-3 and in accordance with the second mode of operation, object 18620-3 is selected and the selection of objects 18620-1 and 18620-2 is maintained, so that objects 18620-1, 18620-2, and 18620-3 are selected.

While objects 18620-1, 18620-2, and 18620-3 are selected, the intensity of contact 18624 is decreased below threshold IT₀, as shown in FIG. 11W. In some embodiments, decreasing the intensity of contact 18624 below threshold IT₀ corresponds to detecting a lift off of contact 18624 from touch-sensitive surface 451. In some embodiments, in response to detection of the decrease in the intensity of contact 18624, objects 18620-1, 18620-2, and 18620-3 are de-selected, as shown in FIG. 11W. In some embodiments, in response to detection of the decrease in the intensity of contact 18624, selection of objects 18620-1, 18620-2, and 18620-3 is maintained.

While the examples described above illustrate the first operation and the second operation as different operations, in some embodiments, the first operation and the second operation are the same type of operation. For example, some embodiments, the first operation and the second operation are both text highlighting operations, but when the device is in the first mode of operation (e.g., because the contact performing the gesture did not reach or exceed IT_(D)) the device would stop highlighting in FIGS. 11I-11J when the intensity of the contact was reduced below the operation-cancellation intensity threshold (e.g., “IT₁”); in contrast, when the device is in the second mode of operation (e.g., because the contact performing the gesture exceeded IT_(D), as shown in FIG. 11G) the device continues highlighting, as shown in FIGS. 11I-11J even when the intensity of the contact is reduced below the operation-cancellation intensity threshold (e.g., “IT₁”). Embodiments where the first and second operations are both document scrolling operations, object selection operations, or object moving operations would be performed in an analogous manner to the highlighting example described above.

FIGS. 12A-12D are flow diagrams illustrating a method 18700 of performing an operation in accordance with a selected mode of operation in accordance with some embodiments. The method 18700 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 18700 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, the method 18700 provides an intuitive way to perform an operation in accordance with a selected mode of operation. The method reduces the cognitive burden on a user when performing an operation in accordance with a selected mode of operation, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to perform an operation in accordance with a selected mode of operation faster and more efficiently conserves power and increases the time between battery charges.

The device displays (18702), on the display, a user interface for the electronic device. For example, in FIG. 11A user interface 18604 is displayed, and in FIG. 11K user interface 18618 is displayed. User interface 18604 includes document 18606, and user interface 18618 includes objects 18620.

The device detects (18704) a sequence of inputs on the touch-sensitive surface, where detecting the sequence of inputs includes (18706) detecting changes in characteristics (e.g., position, speed, intensity, size, rotation) of a respective contact that is continuously detected on the touch-sensitive surface during the sequence of inputs. In some embodiments, the sequence of inputs are made by a single finger contact. For example, FIGS. 11A-11E show a sequence of inputs involving contact 18610. The sequence of inputs includes contact 18610, which is continuously detected on touch-sensitive surface 451, changing in intensity and changing position. Similar sequences of inputs are shown in FIGS. 11F-11J involving contact 18610, in FIGS. 11K-11P involving contact 18624, and in FIGS. 11Q-11W involving contact 18624.

The sequence of inputs includes (18708) a first input and a second input, the first input includes (18710) detecting an increase in intensity of the respective contact (e.g., a press input), and the second input includes (18714) detecting movement of the respective contact on the touch-sensitive surface (e.g., a drag input). For example, the sequence of inputs involving contact 18610, shown in FIGS. 11A-11E, includes an increase in the intensity of contact 18610 (shown in FIGS. 11A-11B) and movement of contact 18610 (shown in FIGS. 11B-11C). The respective sequences of inputs involving contact 18610 (FIGS. 11F-11J), involving contact 18624 (FIGS. 11K-11P), and involving contact 18624 (FIGS. 11Q-11W) also include increases in contact intensity and contact movement. In some embodiments, the first input is (18712) a stationary press input. For example, in FIGS. 11A-11B, the intensity of contact 18610 is increased while contact 18610 is stationary.

In response (18716) to detecting the first input, in accordance with a determination that the first input does not include increasing the intensity of the respective contact above a mode-selection intensity threshold (e.g., “IT_(D)”), the device operates (18718) in a first mode of operation during the second input (e.g., operating in the first (e.g., primary) mode of operation until an input, such as a deep press, that indicates a transition to the second (e.g., alternate) mode of operation is detected), and in accordance with a determination that the first input includes increasing the intensity of the respective contact above the mode-selection intensity threshold (e.g., “IT_(D)”), the device operates (18720) in a second mode of operation, distinct from the first mode of operation, during the second input (e.g., entering the second mode of operation while the contact is continuously detected). For example, in FIGS. 11A-11E, the intensity of contact 18610 is increased, but not above a mode-selection intensity threshold (e.g., “IT_(D)”). In accordance with the intensity of contact 18610 remaining below the mode-selection intensity threshold (e.g., “IT_(D)”), the movement of contact 18610 is detected in accordance with a first mode of operation (e.g., corresponding to document scrolling). In FIGS. 11F-11I, the intensity of contact 18610 is increased above the mode-selection intensity threshold (e.g., “IT_(D)”). In accordance with the intensity of contact 18610 increasing above the mode-selection intensity threshold (e.g., “IT_(D)”), the movement of contact 18610 is detected in accordance with a second mode of operation (e.g., corresponding to text selection).

As a further example, in FIGS. 11J-11P, the intensity of contact 18624 is increased, but not above the mode-selection intensity threshold (e.g., “IT_(D)”). In accordance with the intensity of contact 18624 remaining below the mode-selection intensity threshold, the movement of contact 18624 over objects 18620 is detected in accordance with a first mode of operation (e.g., corresponding to dragging and dropping an object). In FIGS. 11Q-11W, the intensity of contact 18624 is increased above the mode-selection intensity threshold (e.g., “IT_(D)”). In accordance with the intensity of contact 18624 increasing above the mode-selection intensity threshold (e.g., “IT_(D)”), the movement of contact 18624 over objects 18620 is detected in accordance with a second mode of operation (e.g., corresponding to multiple-object selection).

In some embodiments, the second mode of operation is (18722) a contact-intensity-independent mode of operation (e.g., a mode of operation where operations that would otherwise be determined based on an intensity of the contact on the touch-sensitive surface are, instead, determined based on the presence/absence of a contact on the touch-sensitive surface). For example, in FIGS. 11U-11V, objects 18620 continue to be selected in response to cursor 18622 moving over them despite the intensity of contact 18624 decreasing below what would be for example, an operation-cancellation intensity threshold in the first mode of operation (e.g., “IT₁”). Selection is, optionally, cancelled (or, at least, no new object is selected whenever cursor 18622 is moved over the new object) when contact 18624 is lifted off touch-sensitive surface 451 (e.g., as shown in FIG. 11W). As another example, in FIGS. 11I-11J, portions of text 18608 continue to be selected in response to movement of contact 18610 despite the intensity of contact 18610 decreasing below the operation-cancellation intensity threshold in the first mode of operation (e.g., “IT₁”). In either of these examples, changing the intensity of the contact, other than lift the contact off touch-sensitive surface 451, does not affect the operation.

In response to detecting the second input, the device performs (18724) an operation in accordance with the second input based at least in part on whether the device is operating in the first mode of operation or the second mode of operation. For example, in FIGS. 11B-11C, document 18606 is scrolled, in accordance with a first mode of operation, in response to detection of the movement of contact 18610, and in FIGS. 11G-11J, portions of text 18608 are selected, in accordance with a second mode of operation, in response to movement of contact 18610. As another example, in FIGS. 11M-11P, object 18620-1 is dragged and dropped, in accordance with a first mode of operation, in response to movement of contact 18624. In FIGS. 11S-11V, objects 18620-1 through 18620-3 are selected, in accordance with a second mode of operation, in response to movement of contact 18624.

In some embodiments, while (18726) in the first mode of operation, the device starts (18728) to perform a first operation corresponding to the second input, the device detects (18730) a decrease in intensity of the contact below a respective intensity threshold (e.g., IT_(L), IT₁, or a hysteresis intensity threshold associated with IT_(L) that is below IT_(L)), and in response to detecting the decrease in intensity of the contact below the respective intensity threshold (e.g., IT_(L), IT₁, or a hysteresis intensity threshold associated with IT_(L) that is below IT_(L)) while in the first mode of operation, the device ceases (18732) to perform the first operation (e.g., the device determines whether to continue moving an object or drop the object based on whether the intensity of the contact on the touch-sensitive surface drops below the operation-cancellation intensity threshold IT₁ for the first mode of operation).

For example, in FIGS. 11B-11C, document 18606 is being scrolled in response to detection of the movement of contact 18610, where contact 18610 has an intensity between thresholds IT₁ and IT_(D). While document 18606 is being scrolled, the intensity of contact 18610 decreases below a respective threshold (e.g., “IT₁”). In response to detection of the decrease in the intensity of contact 18610 in FIG. 11D while the device is in the first mode of operation, document 18606 ceases to be scrolled, as shown in FIG. 11E, however, in some embodiments, if the device had been in the second mode of operation, the device would have continued to scroll the document.

In another example, in FIGS. 11L-11N, object 18620-1 is selected, picked up, and dragged in response to detection of a gesture including the movement of cursor 18622 over object 18620-1. While object 18620-1 is being dragged, the intensity of contact 18624 decreases below a respective threshold (e.g., threshold IT₁). In response to detection of the decrease in the intensity of contact 18624 in FIG. 11O while the device is in the first mode of operation, object 18620-1 is dropped in user interface 18618 as shown in FIGS. 11O-11P, however in some embodiments, if the device had been in the second mode of operation, the device would have continued to drag object 18620-1.

In some embodiments, the device, while (18734) in the second mode of operation, the device starts (18736) to perform a second operation corresponding to the second input, the device detects (18738) a decrease in intensity of the contact below the respective intensity threshold (e.g., IT_(L), IT₁, or a hysteresis intensity threshold associated with IT_(L)), and in response to detecting the decrease in intensity of the contact below the respective intensity threshold (e.g., IT_(L), IT₁, or a hysteresis intensity threshold associated with IT_(L)) while in the second mode of operation, the device continues (18740) to perform the second operation (e.g., the device continues to move an object based even if intensity of the contact on the touch-sensitive surface drops below the operation-cancellation intensity threshold IT₁ for the first mode of operation).

For example, in FIGS. 11G-11J, a portion of text 18608 is selected in response to detection of the gesture including movement of contact 18610, and while additional text 18608 continues to be selected, the intensity of contact 18610 decreases below a respective threshold (e.g., “IT₁”). In response to detection of the decrease in the intensity of contact 18610 in FIG. 11I while the device is in the second mode of operation, additional text 18608 continues to be selected in response to movement 18618 of contact 18610 in FIGS. 11I-11J, however in some embodiments, if the device had been in the first mode of operation the device would have stopped selecting the text in response to detecting the decrease in intensity of contact 18610 below IT₁ in FIG. 11I.

In another example, in FIGS. 11Q-11V, object 18620-1 is selected in response to detection of the movement of cursor 18622 over object 18620-1, and while cursor 18622 continues moving in response to movement of contact 18624, the intensity of contact 18624 decreases below a respective threshold (e.g., “IT₁”). In response to detection of the decrease in the intensity of contact 18624 in FIG. 11U while the device is in the second mode of operation, the device continues to select additional objects (e.g., objects 18620-2 and 18620-3) when cursor 18622 is moved over them, however in some embodiments, if the device had been in the first mode of operation the device would have stopped selecting the objects in response to detecting the decrease in intensity of contact 18624 below IT₁ in FIG. 11U.

In some embodiments, in the first mode of operation, the second input corresponds to (18742) a first operation (e.g., dropping an object), and in the second mode of operation, the second input corresponds to a second operation different from the first operation (e.g., continuing to move the object). Thus, in some embodiments, the second input has a different meaning in the first mode of operation than it does in the second mode of operation. For example, in FIGS. 11K-11P, movement of a contact in the first mode of operation corresponds to dragging-and-dropping an object (e.g., movement of contact 18624), however, in some embodiments, in the second mode of operation (e.g., where contact 18624 exceeds IT_(D)), the device would continue to move object 18620-1 even after the intensity of contact 18624 decreased below the operation-cancellation intensity threshold (e.g., “IT₁”), until liftoff of contact 18624 is detected.

In some embodiments, the first operation includes (18744) scrolling an electronic document, and the second operation includes selecting content in the electronic document. For example, in FIGS. 11A-11J, movement of a contact in the first mode of operation corresponds to document scrolling (e.g., movement of contact 18610 in FIGS. 11A-11E), and movement of the contact in the second mode of operation corresponds to content (e.g., text) selection (e.g., movement of contact 18610 in FIGS. 11F-11J).

In some embodiments, the first operation includes (18746) moving a user interface object in a user interface, and the second operation includes selecting a plurality of user interface objects in the user interface. For example, while in the first mode of operation, the device deselects a currently selected user interface object upon detecting a decrease of intensity of a contact below an object-deselection intensity threshold (e.g., “IT₁”). Conversely, while in the second mode of operation, the device maintains selection of the currently selected user interface object even after detecting a decrease in intensity of the contact below the object-deselection intensity threshold (e.g., “IT₁”) until liftoff of the contact, another deep press gesture, or other predefined input is detected that exits the second mode of operation. In FIGS. 11K-11W, movement of a contact in the first mode of operation corresponds to moving (e.g., dragging-and-dropping) an object (e.g., movement of contact 18624 in FIGS. 11K-11Q), and movement of the contact in the second mode of operation corresponds to multiple-object selection (e.g., movement of contact 18624 in FIGS. 11Q-11V).

In some embodiments, in response to detecting the first input, the device starts (18748) to perform a respective operation (e.g., “pick up and move” a user interface object), and in response to detecting the second input, the device continues to perform the respective operation (e.g., “continue to move” the previously picked up user interface object). For example, in FIGS. 11K-11P, object 18620-1 is “picked up” in response to an increase in the intensity of contact 18624 above threshold IT_(L) while cursor 18622 is over object 18620-1, and object 18620-1 is moved in response to movement 18628 of contact 18624 after object 18620-1 is picked up.

In some embodiments, the device detects (18750) an increase in intensity of the respective contact above a first intensity threshold (e.g., an object-selection intensity threshold such as IT_(L)) while a focus selector corresponding to the contact is at or proximate to a respective user interface object. In response to detecting the increase in intensity of the respective contact above the first intensity threshold (e.g., IT_(L) or IT_(D)), the device generates (18752) a tactile output on the touch-sensitive surface that corresponds to selection of the respective user interface object. After (18754) detecting the increase in intensity of the respective contact above the first intensity threshold (e.g., IT_(L) or IT_(D)), the device detects (18756) a decrease in intensity of the respective contact below a second intensity threshold (e.g., an object-drop intensity threshold such as IT₁) while the focus selector is at or proximate to the respective user interface object. In response to detecting the decrease in intensity of the respective contact below the second intensity threshold (e.g., IT_(L), IT₁ or a hysteresis threshold associated with IT_(L) that is below IT_(L)), in accordance with the determination that the device is in the first mode of operation, the device deselects (18758) the respective user interface object and generates (18760) a tactile output corresponding to deselecting the respective user interface object; and in accordance with the determination that the device is in the second mode of operation, the device maintains (18762) selection of the respective user interface object and forgoes generation of the tactile output corresponding to deselecting the respective user interface object.

For example, in FIGS. 11K-11P, a tactile output is optionally generated in response to the increase in the intensity of contact 18624 above a first intensity threshold (e.g., “IT_(L)”) while cursor 18622 is over object 18620-1 in FIG. 11M (indicating selection and pick-up of object 18620-1), and a tactile output is optionally generated in response to the decrease in the intensity of contact 18624 below a second intensity threshold (e.g., “IT₁”) while cursor 18622 is over object 18620-1 in FIG. 11O (indicating de-selection and dropping of object 18620-1). In FIGS. 11Q-11W, a tactile output is optionally generated in response to the increase in the intensity of contact 18624 above threshold IT_(L) while cursor 18622 is over object 18620-1 in FIG. 11S (indicating selection of object 18620-1), and a tactile output is not generated in response to the decrease in the intensity of contact 18624 below second intensity threshold (e.g., “IT₁”) but remaining above threshold IT₀ (e.g., because the device does not drop or de-select object 18620-1) in FIG. 11V.

Thus, in some embodiments, while the device is in the first mode of operation, the device generates tactile outputs so that the user feels a click when increasing past an object-pickup intensity threshold and also when decreasing past an object-drop intensity threshold (e.g., because objects are being picked up and dropped). In contrast, while the device is in the second mode of operation, the device generates tactile outputs so that the user feels a click when increasing past an object-pickup intensity threshold, but does not feel a click when decreasing past object-drop intensity threshold (because objects are not being dropped). Thus, in some embodiments, the first mode of operation provides similar tactile outputs to those that would be expected from a physical actuator, while the second mode of operation provides tactile outputs that correspond more closely to the operations being performed in the user interface, even if additional tactile outputs that would have been generated by a physical actuator are not performed (e.g., the device has the ability to output multiple “down click” tactile outputs without outputting a corresponding number of “up click” tactile outputs).

It should be understood that the particular order in which the operations in FIGS. 12A-12D have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) are also applicable in an analogous manner to method 18700 described above with respect to FIGS. 12A-12D. For example, the contacts, user interface objects, tactile outputs, intensity thresholds, and focus selectors described above with reference to method 18700 optionally have one or more of the characteristics of the contacts, user interface objects, tactile outputs, intensity thresholds, and focus selectors described herein with reference to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments). For brevity, these details are not repeated here.

In accordance with some embodiments, FIG. 13 shows a functional block diagram of an electronic device 18800 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in FIG. 13 are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

As shown in FIG. 13, an electronic device 18800 includes a display unit 18802 configured to display a user interface for the electronic device, a touch-sensitive surface unit 18804 configured to receive inputs, one or more sensors 18806 configured to detect intensity of contacts with the touch-sensitive surface unit 18804, and a processing unit 18808 coupled to the display unit 18802, the touch-sensitive surface unit 18804, and the sensors 18806. In some embodiments, the processing unit 18808 includes a detecting unit 18810, an operating unit 18812, a performing unit 18814, a starting unit 18816, a ceasing unit 18818, a continuing unit 18820, a generating unit 18822, a deselecting unit 18824, and a maintaining unit 18826.

The processing unit 18808 is configured to: detect a sequence of inputs on the touch-sensitive surface unit 18804 (e.g., with the detecting unit 18810), wherein: detecting the sequence of inputs includes detecting changes in characteristics of a respective contact that is continuously detected on the touch-sensitive surface unit 18804 during the sequence of inputs, the sequence of inputs includes a first input and a second input, the first input includes detecting an increase in intensity of the respective contact, and the second input includes detecting movement of the respective contact on the touch-sensitive surface unit 18804; in response to detecting the first input: in accordance with a determination that the first input does not include increasing the intensity of the respective contact above a mode-selection intensity threshold (e.g., “IT_(D)”), operate in a first mode of operation during the second input (e.g., with the operating unit 18812), and in accordance with a determination that the first input includes increasing the intensity of the respective contact above the mode-selection intensity threshold (e.g., “IT_(D)”), operate in a second mode of operation, distinct from the first mode of operation, during the second input (e.g., with the operating unit 18812); and in response to detecting the second input, perform an operation in accordance with the second input based at least in part on whether the device is operating in the first mode of operation or the second mode of operation (e.g., with the performing unit 18814).

In some embodiments, the first input is a stationary press input.

In some embodiments, the second mode of operation is a contact-intensity-independent mode of operation.

In some embodiments, the processing unit 18808 is configured to, while in the first mode of operation: start to perform a first operation corresponding to the second input (e.g., with the starting unit 18816), detect (e.g., with the detecting unit 18810) a decrease in intensity of the contact below a respective intensity threshold (e.g., “IT₁”), and in response to detecting the decrease in intensity of the contact below the respective intensity threshold (e.g., “IT₁”) while in the first mode of operation, cease to perform the first operation (e.g., with the ceasing unit 18818).

In some embodiments, the processing unit 18808 is configured to, while in the second mode of operation: start to perform a second operation corresponding to the second input (e.g., with the starting unit 18816), detect (e.g., with the detecting unit 18810) a decrease in intensity of the contact below the respective intensity threshold (e.g., “IT₁”), and in response to detecting the decrease in intensity of the contact below the respective intensity threshold (e.g., “IT₁”) while in the second mode of operation, continue to perform the second operation (e.g., with the continuing unit 18820).

In some embodiments, in the first mode of operation, the second input corresponds to a first operation, and in the second mode of operation, the second input corresponds to a second operation different from the first operation.

In some embodiments, the first operation includes scrolling an electronic document, and the second operation includes selecting content in the electronic document.

In some embodiments, the first operation includes moving a user interface object in a user interface, and the second operation includes selecting a plurality of user interface objects in the user interface.

In some embodiments, the processing unit 18808 is configured to: in response to detecting the first input, start to perform a respective operation (e.g., with the starting unit 18816), and in response to detecting the second input, continue to perform the respective operation (e.g., with the continuing unit 18820).

In some embodiments, the processing unit 18808 is configured to: detect an increase in intensity of the respective contact above a first intensity threshold (e.g., IT_(L) or IT_(D)) while a focus selector corresponding to the contact is at or proximate to a respective user interface object (e.g., with the detecting unit 18810); in response to detecting the increase in intensity of the respective contact above the first intensity threshold (e.g., IT_(L) or IT_(D)), generate a tactile output on the touch-sensitive surface unit 18804 that corresponds to selection of the respective user interface object (e.g., with the generating unit 18822); and after detecting the increase in intensity of the respective contact above the first intensity threshold (e.g., IT_(L) or IT_(D)): detect a decrease in intensity of the respective contact below a second intensity threshold (e.g., IT_(L), IT₁ or a hysteresis threshold associated with IT_(L) that is below IT_(L)) while the focus selector is at or proximate to the respective user interface object (e.g., with the detecting unit 18810), and in response to detecting the decrease in intensity of the respective contact below the second intensity threshold (e.g., IT_(L), IT₁ or a hysteresis threshold associated with IT_(L) that is below IT_(L)): in accordance with the determination that the device is in the first mode of operation, deselect the respective user interface object (e.g., with the deselecting unit 18824) and generating a tactile output corresponding to deselecting the respective user interface object (e.g., with the generating unit 18822), and in accordance with the determination that the device is in the second mode of operation, maintain selection of the respective user interface object (e.g., with the maintain unit 18826) and forgo generation of the tactile output corresponding to deselecting the respective user interface object (e.g., with the generating unit 18822).

The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to FIGS. 1A and 3) or application specific chips.

The operations described above with reference to FIGS. 12A-12D are, optionally, implemented by components depicted in FIGS. 1A-1B or FIG. 13. For example, detection operation 18704, operating operations 18718 and 18720, and performing operation 18724 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.

It should be understood that the particular order in which the operations have been described above is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that the various processes separately described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) can be combined with each other in different arrangements. For example, the contacts, user interface objects, tactile sensations, intensity thresholds, and/or focus selectors described above with reference to any one of the various processes separately described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) optionally have one or more of the characteristics of the contacts, gestures, user interface objects, tactile sensations, intensity thresholds, and focus selectors described herein with reference to one or more of the other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments). For brevity, all of the various possible combinations are not specifically enumerated here, but it should be understood that the claims described above may be combined in any way that is not precluded by mutually exclusive claim features.

However, the illustrative discussions above are not intended to be exhaustive or to limit the various described embodiments to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings.
